Amazing Rechargeable Flashlight Benefits
By Saji Nase

The flashlight has made large strides in progress from a simple bright long lasting LED lights, to solar rechargeable flashlights. Traditional flashlights used alkaline batteries, their lights were not meant to be used for long periods of time, and the lights were very dim. New technology improved upon the function and design of traditional flashlights, but these flashlights still needed their environmentally damaging alkaline batteries to be replaced frequently. In addition to battery replacement, traditional flashlights are often broken easily, and the quality of their light is still not very good. Thus the ever important need for a cost effective solution was born.

To solve the many problems of the traditional flashlights, many different types of rechargeable flashlights were developed. Most of the flashlights used, use a dry cell to recharge the flashlight bulb. The rechargeable flashlight is more durable, the light quality is more luminous, and they are less damaging to the environment than traditional flashlights. A variety of different models of the original rechargeable flashlight are now on the market. Some styles use electricity to recharge, some are powered by solar energy, and the bulbs in the flashlight can be Xenon, halogen, or LED lights. So, you can see how just how advanced the flashlight has become from the old days.

You should really check out these two popular flashlights, if you are interested in getting a rechargeable flashlight for your home: the Kaito Self-Powered 5-LED Dynamo Hand Crank Rechargeable Emergency Flashlight, and the Streamlight Ultra Stinger Xenon Rechargeable Flashlight with Charger. Recognized for their quality and toughness, the Kaito Self Powered rechargeable flashlight includes 5 bright white LED lights. This light is almost twenty times more luminous than earlier models of flashlights. For working outdoors, you may want to look into purchasing the water resistant flashlight that can be used in the extreme outdoors.

The Streamlight Ultra Stinger Xenon rechargeable flashlight is a light weight flashlight, yet it is capable of producing a candlepower up to 75,000. This highly bright light enables a person to precisely focus the light onto any object from far away. But, as always there are going to be advantages and disadvantages to any flashlight you choose. Now, don’t be lazy, and make sure that you do proper research when choosing the flashlight that’s right for you.

Buying the right flashlight

It is a hard to find the right flashlight. You read through hundreds of flashlight reviews and descriptions and it just seems impossible to find the right flashlight for your needs. This article should help!

Locating The Right Flashlight To Meet Your Needs
By Reagan Whitley

When trying to decide on the best flashlight you can use make sure you really give things such as buying one that is equipped with a head design some thought, because when you put it down you don’t want it rolling away from you. It’s important to find a flashlight that produces a white light that’s bright when you use it and it should also have the ability to blind an attacker if needed. Your flashlight has to be able to handle the tough weather or be in a particular price range, and it should certainly have different levels of light. Each one of these are definitely valid requirements for a flashlight, and check out a listing of features that’ll assist you with identifying what kind of flashlight will work the very best when it comes to your particular needs.

Your Shopping List
Be sure you ask yourself a few of these questions before you make the decision to get yourself a flashlight. Are you aware of the difference between xenon bulb and LED? Are the batteries re-chargeable? Are you looking for a flashlight that’s not that big in size or do you need one that’s very large? Let’s talk about all of the features of the most common flashlights that you can purchase.

Tip #1 Altering the Intensity
The intensity adjustment is definitely one of the most common features of the modern day flashlight. If you have specific illumination requirements then these are the type of flashlights you must have. When it comes to a common household flashlight changing the intensity of the light is not something you really want. This feature will cost you much more money but will provide you with the light power of many flashlights in one. A number of different intensity levels will be available with the most effective tactical flashlight.

Tip #2 Range and Output
Regardless if you are making use of your flashlight for hiking, outdoor camping, hunting, safety or for protection, the output and the range of the illumination is completely different for each situation. The distance of your light beam is probably not of such worry for domestic usage because it would be for backpacking or for camping out. Lumens is the standard in the field to measure intensity. The typical household flashlight will be somewhere around 10 to 100 lumens. In addition to the lumens, how clean the beam will be and the specific distance the light can travel is what the manufacturers will tell you. Both hunters and campers usually find this feature very helpful.

Tip #3 The Settings of Operation
Your flashlight’s settings are a number of settings of light intensity the flashlight will output. Though domestic flashlights are okay with a couple of settings, campers and hikers would do better working with flashlights that have 4 or more modes. The reason being is that if you’re in a fairly illuminated place you can get away with a low mode that won’t utilize but 15 or more lumens, guaranteeing that if you want the power of 500 or more lumens deep inside the woods, you will have the power.

Tip #4 The LED Flashlight Bulb
Incandescent bulbs are what older flashlights used, which did not last too long and did not have an extremely vivid light output either. A flashlight that uses a LED bulb is always a good idea. The most efficient LED flashlights can last about 10,000 hours before they need to get swapped out, and they put out an extremely brighter beam that the incandescent bulbs cannot match.

Tip #5 How big is the Flashlight
The weight and size of the flashlight are among the most important things you should need to give some though when selecting a flashlight. Since you’ll be carrying your light as well as a lot of other supplies the most effective tactical flashlight will be very lightweight. You can look for a blend of a lighter weight flashlight that has the lumens you will need.

Tip #6 Normal and Rechargeable Batteries
Deciding on battery versus run time is one of the toughest decisions you’ll need to make when you choose a flashlight. A number of flashlights make use of battery power more quickly compared to others, and it really depends if you want to acquire more affordable batteries that will only last one time versus the higher priced rechargeable batteries that may be used frequently over. The best flashlight that’s rechargeable will allow you to use different sized batteries within the flashlight.

Tip #7 The Value of the Flashlight
How much you’ll be able to spend on your flashlight will mainly depend on your budget, but that doesn’t mean you should get the biggest flashlight out there. Compare every feature we previously mentioned and attempt to make the most features possible for your financial budget. Regardless if you’re a professional maintenance man, in law enforcement or an avid outdoorsman and require a flashlight for survival, maintenance or safety, including the best features and remaining in your spending budget will guarantee you get the most for the amount of money you spend.

This is how an LED works

I think LED flashlights and light bulbs are a wonder of science and an amazing achievement in lighting! Because of LED lightbulbs we have smaller and more energy efficient, brighter flashlights!

How Do LEDs Work?
By Eric Bornfriend

Light emitting diodes or LEDs for short, are found in a multitude of different electronics. From remote controls, to traffic lights, to TVs, they truly are a staple of the electronics world.

LEDs are nothing more than very small light bulbs with two metal leads coming out that can easily be attached to a circuit. So what makes LEDs so special? you may be asking. What makes LEDs so special is that they don’t have a filament like other “normal” light bulbs, therefore there is nothing to burn out and nothing to produce heat, making them last infinitely longer than traditional light bulbs. Instead, the light is created by nothing more than the rapid movement of electrons in a semiconductor. The amount of power or electricity needed to move the electrons is far less than what is needed to illuminate traditional light bulbs. In a traditional light bulb, usually more than 80% of the electricity used to illuminate the bulb is converted to heat put off by the filament.

LED lights are available in a variety of different colors, for a variety of different applications. The easiest colors to produce are red, yellow, and green, while white remains the hardest LED color to produce. It is so difficult that a pure white LED light is not even available on the market today. The closest is a whitish-blue which is created by mixing red, green, and blue colored LEDs to produce white.

Inside an LED, you will find a semiconductor diode in which one side is attached to an anode and the other side attached to a cathode. Electricity flows in only one direction. From the anode to the cathode. When the electrical current passes through in this direction, the electrons flow through the semiconductors and switch to different energy levels. When this change in energy levels occurs, the electrons emit a photon of light. These photons of light are then focused through a lens to provide the light that we see.

Here is a great LED Flashlight you should try!

Defend yourself with a flashlight

You read the title correctly! Yes, you can use your powerful flashlight to defend yourself. Use the bright light to blind someone or even hit them with your flashlight! You can even use your flashlight to signal for help.

Read the following article and below you will find our choice for a flashlight for defense!

Choosing the Best Flashlight for Self-Defense
By Alex Manire

Many of my self-defense students have questions about flashlights. As with most categories of equipment that fall within the tactical or self-defense genre, there are simply too many options to truly capture the whole topic with a short article. What I would like to do, however, is hit some of the more general topics that are not common knowledge for most people. This article does not cover every possibility or situation; I’m only trying to give enough general knowledge to enable someone who has no experience of any kind to feel like they can begin looking for the right light.

Let’s start with a brief sum-up of why flashlights make such wonderful tools. Most people think of a tactical flashlight and immediately think of the big MagLite that can be used to knock out a Yeti. I would like to point out that in the event someone is attacking me, I’ll be all too happy to hit them with just about anything I can get my hands on. While a large MagLite is an option, a good flashlight can be used much more effectively, and it won’t have to be something that you need a backpack to carry. A good flashlight can be used to control, disorient, and confuse an attacker in low to normal light situations. So, indeed, it is the light part of flashlight that is the key to making it a wonderful tool.

When shopping for a flashlight, you will find two main types of lighting methods – incandescent and LED. Incandescent is the light that most people are used to seeing. It consists of a single filament light bulb that sticks through the head of the light at the base of the lens housing. The bulb is protected by a plastic or glass cover. These flashlights can, in fact, burn quite brightly; but remember that in a way they are burning. They produce a lot of heat and can be a little fragile; their filaments may not take much abuse. These lights will flood an area with light that’s almost yellowish in color. The beam usually can be focused or unfocused to achieve the desired light ring. The versatility of the size of beam is a good feature, but the user needs to know how to quickly change the focus for a given situation. There are exceptions to every rule, but generally speaking, simple, incandescent lights will cost a little less to purchase.

Light-Emitting Diode (LED) flashlights are the other readily available type. The engineering of the light is beyond the scope of this article, but you do need to know how to compare the two lights. If incandescent light could be compared to a normal 60W light bulb, an LED would be compared to the light emitted by the screen on your iPhone. Therefore, there are usually multiple LEDs in the head of the flashlight. LED flashlights give off light that has a slight bluish tinge. Because there are more individual light sources, the light emitted is usually a little more evenly distributed throughout the beam, and very little heat is produced while these lights are on. Another big bonus is that they are a little harder to break with a bump, hit, or shock of some kind. For this reason, you’ll find that a great many weapon mounted lights are LED since they handle the shock of the firearm discharging rather well.

A final technical consideration for a flashlight is its lumen level. Lumens are the measure for how bright a light appears. For the most part, the 50- 80 lumens range is perfect to see things in the dark. But for self-defense, I usually prefer the 150-180 lumens range, possibly even more.

When picking a flashlight, several key questions should be considered. If you address these questions while researching your light, you’ll end up with one that’s better suited to your personal needs and likes.

The first question you should consider is the size of the flashlight. Will the flashlight be able to be worn or carried easily without getting in the way of my normal routine? For this reason alone, I tend to not carry the biggest flashlight I can find. There are plenty of pocket-sized lights that are powerful.

The next question is about getting your hands on the flashlight. Will I be able to access it quickly and in the dark without needing to look for it? This might seem like common-sense, but I’ve seen it overlooked many times.

Another question has to do with function. Does the light have a good track record of being used in the situations I’m planning to need it for? I wouldn’t want to take a two dollar key chain flashlight with me in a very dark forest with a lot of obstacles. There’s just not enough power to the light to show me the things I need to see, and there’s almost no range to them.

Range is another very important consideration. How far I can see with my light is not the same as the distance my light can be seen by someone else. I need to consider the target I make when I turn on my flashlight as much as I need to consider my need to see around me. Again, training and practice are the best ways to compensate for these situations. There are methods that can help reduce risk while using a light in a dangerous situation, but you need to learn these techniques from an experienced instructor.

If I need the light to produce a large amount of light, will it be enough to stun or blind someone for an instant? Again, I look for the capability to hit that 150 or higher lumens range, but I also try to pick one that doesn’t ALWAYS operate in that range because sometimes I just need a flashlight.

Does the flashlight have the ability to be turned on and off VERY quickly? I tend to lean toward pressure buttons here; if I’m adding pressure it’s on, and if not, it’s off – pretty simple.

Does it have the ability to remain on at the level of light I need? Again, sometimes I need a flashlight to just be a flashlight. If my pressure button doesn’t also have a way to turn the light on and leave it on, then I tend not to use it.

Will the light function as a light? More to the point, will this tool actually prove useful when I need it? Will I be able to adjust the beam, the brightness, and the features quickly and appropriately for a given situation. One of my friends told me of a time when he was a young police officer. He chased an assailant up a tree, and with five other officers there, he pulled out his new flashlight that simply drowned out all the other lights around him. He told me that he learned “that the man with the brightest light is apparently the one in charge.”

Does the light have other ‘special’ features? There are some lights that have little beveled edges around one end or another. These can easily be used for self-defense. I think it’s worth mentioning them, but I usually tend to use a flashlight as a flashlight. If I have to hit someone, I’ll find something harder and more clumsy; rocks or chairs work great. However, when there’s nothing else available, it’s nice to know I have the option if needed. Lasers can also be found on some lights, but lights with this option usually are made to be mounted on a firearm. Since many who carry a flashlight will not be carrying a firearm, and weapon mounted lights are a special topic, it is beyond the intended scope of this article to consider laser options.

Is the flashlight simple enough to actually use without activating a ‘special’ option by accident? Some lights have strobe options that are disorienting to attackers, but strobing light can also cause the same disorientation in the user. I distinctly remember trying to do a low-light pistol course, and my strobe option kept turning on when I was trying to make my shot. Strobes are great for signaling or disorienting someone, but when I’m trying to make a shot with my pistol, it tends to disorient me instead.

With flashlights, as with any other item that has a high failure rate, if you carry one… carry two. For items that can fail you, it’s always a good idea to have a back-up. I actually carry two flashlights on me, or I have one nearby that will be easily accessible perhaps in my vehicle or in an outside pocket of my pack that I can quickly find.

Some people want to know what flashlight I prefer. I tend to like lights that are LED, have a thumb pressure control switch with the ability to leave the light on somehow if I choose, and have at least two settings – one around 50 lumens and the other around 180 lumens. I would rather spend a little more money on exactly what I want, knowing it’ll be around for a long time, rather than just get something inexpensive that I might have to replace too soon. Many manufacturers offer a wide variety of lights. I suggest that, as you research and choose a light that meets your needs, you also ask whether others who have similar needs and requirements choose the brand that you are considering.

As with almost every piece of equipment that’s out there, always keep in mind that the more time and thought you put into it, the better choice you’ll make. Most important of all is once you have your light, practice with it the way you’re going to have to use it when the time comes. Low light training classes are an entire course by themselves at nearly every self-defense style training school in the world. Training and practice are the essential keys to having self-confidence in potentially dangerous situations whether it is the use of flashlights or any other tool or weapon.

How to survive a power outage!

Power outages in this technological age are very different than they used to be in terms of how we survive. In a world where technology is the root of day to day activity sometimes people might forget that it is possible for the electricity to go out, then what do you do? Recently the Merrimack Community experienced a school wide power outage and staff and students had to do things the “old fashioned” way.

The first thing that crossed the minds of students is if their electronic devices were charged. Many of them found themselves figuring out how long they would be disconnected for. When the college learned that it would take days for the power to be restored, students were encouraged to go home or stay with friends who had power if they could. In situations that cause the loss of power, it is best to be prepared even if the scenario is only a possibility as you never know when the power might be out for days.

Gone are the days in which people passed the time by playing board games. Now, there are ways in which people can still use their electronic devices during a power outage. With the technology we have today there are many different devices that can help you through a time without electricity, one of these devices is a portable battery charger that connects via usb and is used to recharge devices. Mophie makes Apple and Android compatible chargers that are perfect to keep fully charged ready to go.

Another tool that students should have at the ready is a flashlight. This seems pretty obvious but with there being a flashlight button of most smartphones these days it might be less obvious than most might feel, something to go along with the flashlight is a pack of extra batteries because it might be a few days before the power comes back on.

When the power does go out and the battery on your phone and computer has finally run out what is there to do? The first thing that a student might face is having to talk to their roommate to pass the time. Another task that is very accomplishable while the electricity is out would be getting any school or internship paperwork together and complete what can be with the free time you have, you could also fold your laundry, but it would be best to pick the lesser of two evils.

Now just because the electricity is out does not mean you need to hunker down for the long haul. You could use the down time to get some shopping done, as most major retailers will have backup generators it is very possible the store is open for business. Take time to use the flashlight you had prepared to look around the room for items you need or could use to pass the time, these items being water, food that should not be perishable as you will not know when the electricity will come back on. As for what to do to pass the time, things like board games will do and who knows you and your roommates might actually have a good time.

Now that we are in the thick of the power outage students might start to shake a little as they have been disconnected from social media for a couple of days now, and this brings us to a heavily talked about topic in today’s society. 1 in 3 people will wake up during the middle of the night and use that time to check social media according to the Huffington Post. This is a very surprising fact but not something that is not believable as a vast majority, if not all, students are connected to social media and often check into that social media. Now what do a bunch of college students to when they are faced with the challenge of not being connected for days at a time? Well they hang on as long as there is battery life then it is just up to preparation and an open mind.

The History of the Flashlight

In 1887, the first dry cell battery was invented. Unlike previous batteries, it used a paste electrolyte instead of a liquid. This was the first battery suitable for portable electrical devices, as it did not spill or break easily and worked in any orientation. The first mass-produced dry cell batteries came in 1896, and the invention of portable electric lights soon followed. Portable hand-held electric lights offered advantages in convenience and safety over (combustion) torches, candles and lanterns. The electric lamp was odorless, smokeless, and emitted less heat than combustion-powered lighting. It could be instantly turned on and off, and avoided fire risk.

On January 10, 1899, British inventor David Misell obtained U.S. Patent No. 617,592, assigned to American Electrical Novelty and Manufacturing Company. This “electric device” designed by Misell was powered by “D” batteries laid front to back in a paper tube with the light bulb and a rough brass reflector at the end. The company donated some of these devices to the New York City police, who responded favorably to them.
The angle-head flashlight on the left uses an incandescent bulb, while the adjustable angle-head flashlight on the right uses LEDs to give white, red, blue, and infrared light

Carbon-filament bulbs and fairly crude dry cells made early flashlights an expensive novelty with low sales and low manufacturer interest. Development of the tungsten-filament lamp in 1904, with three times the efficacy of carbon filament types, and improved batteries, made flashlights more useful and popular. The advantage of instant control, and the absence of flame, meant that hand-held electric lights began to replace combustion-based lamps such as the hurricane lantern. By 1922 several types were available; the tubular hand-held variety, a lantern style that could be set down for extended use, pocket-size lamps for close work, and large reflector searchlight-type lamps for lighting distant objects. In 1922 there were an estimated 10 million flashlight users in the United States, with annual sales of renewal batteries and flashlights at $20 million, comparable to sales of many line-operated electrical appliances.[6] Flashlights became very popular in China; by the end of the 1930s, 60 companies made flashlights, some selling for as little as one-third the cost of equivalent imported models. Miniature lamps developed for flashlight and automotive uses became an important sector of the incandescent lamp manufacturing business.

Flashlight Performance standards

Pay attention to Flashlight performance Standards when you buy a flashlight top be sure you are getting the flashlight you need.

The United States Army former standard MIL-F-3747E described the performance standard for plastic flashlights using two or three D cell dry batteries, in either straight or angle form, and in standard, explosion-proof, heat-resistant, traffic direction, and inspection types. The standard described only incandescent lamp flashlights and was withdrawn in 1996.

In the United States, ANSI in 2009 published FL1 Flashlight basic performance standard. This voluntary standard defines test procedures and conditions for total light output, beam intensity, working distance, impact and water resistance, and battery running time to 10% of initial light output. The FL1 standard gives definitions for terms used in marketing flashlights, with the intention of allowing the consumer to compare products tested to the standard.[19] The standard recommends particular graphic symbols and wording for the product package, so that the consumer can identify products tested to the standard. Testing may be carried out by the manufacturer itself or by a third-party test laboratory.

The FL1 standard requires measurements reported on the packaging to be made with the type of batteries packaged with the flashlight, or with an identified type of battery. Initial light output is measured with an integrating sphere photometer, 30 seconds after the light is switched on with fresh (or newly charged) batteries. The total light emitted is reported in lumens. Luminous intensity is determined by measuring the brightest spot in the beam produced by the flashlight, in candelas. Since this is a measure of all the light emitted in a solid angle (the “cone” of light in a particular direction), the beam intensity is independent of distance.

The working distance is defined as the distance at which the maximum light falling on a surface (illuminance) would fall to 0.25 lux. This is comparable to a full moon on a clear night. The distance is calculated from the square root of (the beam intensity in candelas divided by 0.25 lux); for example, a beam intensity of 1000 candelas produces a working range rating of the square root of (1000/0.25), or 63 meters. The result is reported in meters or feet. The working distance is from the point of view of the user of the flashlight. A light directly pointed at an observer may be visible against a dark background for many times this distance, especially if the observer has night-vision equipment.

Run time is measured using the supplied or specified batteries and letting the light run until the intensity of the beam has dropped to 10% of the value 30 seconds after switching on. The standard does not evaluate the behavior of the flashlight output during run time. A regulated flashlight may run at only a slowly declining output and then abruptly cut off, but unregulated types may have steeply-declining light output after only a short time. Manufacturers of headlamps may use a different standard which rates run times until light output falls to 1 lux at 2 meters distance; this value is not comparable to the FL 1 runtime measurement.

Impact resistance is measured by dropping the flashlight in six different orientations and observing that it still functions and has no large cracks or breaks in it; the height used in the test is reported. Water resistance, if specified, is evaluated after impact testing; no water is to be visible inside the unit and it must remain functional. Ratings are given in IP Code terms, where jet spray corresponds to IP X6, brief immersion to IPX7, 30 minutes immersion at 1 meter or more is IP X8; (the depth is reported if greater than 1 meter). An IP X8 rating by FL1 does not imply that the lamp is suitable for use as a diver’s light since the test protocol examines function of the light only after immersion, not during immersion.[20]

The consumer must decide how well the ANSI test conditions match their requirements, but all manufacturers testing to the FL1 standard can be compared on a uniform basis. The light measurements are more directly related to the use of flashlights than is the nominal power input to the lamp (watts), since different LED and incandescent lamp types vary widely in the amount of light produced per watt. Even the same LED or lamp in different optical systems will show different beam characteristics. The visibility of objects depends on many factors as well as the amount of light emitted by the flashlight.

ANSI standard FL1 does not specify measurements of the beam width angle but the candela intensity and total lumen ratings can be used by the consumer to assess the beam characteristics. Where two flashlights have similar total light (lumen) measures, the unit with the higher candela rating produces a more concentrated beam of light, suitable for lighting distant objects; it will also have a higher working distance. If two lights have similar candela ratings, the light with higher lumen value will produce a wider beam and will light a wider area overall. A beam width (containing most of the power of the beam, or “hot spot”) of a few degrees corresponds to a spot light, useful for searching for distant objects; beam widths of 20 degrees or more are described as flood lights, suitable for lighting a wide nearby area. Typically even a flashlight beam with a small hot spot will have some light visible as “spill” around the spot.

What is a flashlight?

This is the definition of a flashlight according to Wiki:

A flashlight (often called a torch outside North America) is a portable hand-held electric light. Usually, the source of the light is an incandescent light bulb or light-emitting diode (LED). A typical flashlight consists of a light bulb mounted in a reflector, a transparent cover (sometimes combined with a lens) to protect the light source and reflector, a battery, and a switch. These are supported and protected by a case.

The invention of the dry cell and miniature incandescent electric light bulbs made the first battery-powered flashlights possible around 1899. Today flashlights use mostly incandescent lamps or light-emitting diodes and run on disposable or rechargeable batteries. Some are powered by the user turning a crank or shaking the lamp, and some have solar panels to recharge a battery.

In addition to the general-purpose hand-held flashlight, many forms have been adapted for special uses. Head or helmet-mounted flashlights designed for miners and campers leave the hands free. Some flashlights can be used underwater or in flammable atmospheres. Flashlights are used as a light source when in a place with no power.
