LED flashlights are gaining in popularity nowadays. They have become a must-have gadget for those who love camping, hiking, exploring, or any other outdoor activity. In fact, LED flashlight has become a must-have gadget to keep at home, as well.
Over the years, LED flashlights have replaced the traditional flashlights which consisted of the old incandescent bulb. The LED torch, which is how they are known in some other countries, is far better than traditional flashlights.
LED Technology
The bright LED flashlight consists of light emitting diodes. LEDs are used widely used in watches, remote controls, traffic lights and television. When the LED technology is applied to flashlights, they produce better and long lasting flash light.
In order to understand the LED technology and how it is better, we need to compare it with the traditional incandescent bulb. The ordinary bulb consists of a filament wire which is enclosed in a glass vacuum tube. When electricity passes through this wire, it glows and gives out light.
How LED Flashlight Works
In LED tactical flashlights, light is generated through a different process. LED consists of two types of semiconductor materials. One type of material has a lot of free electrons while the other type of material lacks free electrons. When electricity is supplied to a LED flashlight, the free electrons in the abundant material jump to the material that is deficit in free electrons.
When the electrons move to the deficit material, they release a particle called photon, which is a light particle. This is how light is generated in LED camping lanterns.
Measuring Brightness
LED flashlights are brighter than traditional flashlights. In a LED flashlight, brightness is measured by a unit called lumens. Most flashlights are available in the range of 10 to 100 lumens.
A 10 lumens flashlight is used for practical purposes. If you want a flashlight bright enough to light up the passage when you go for a walk in the dark, then a 30 lumens flashlight is what you need.
Police and military forces use super bright flashlights of more than 90 lumens. Some of these flashlights offer several hundred lumens. These bright flashlights are also known as LED tactical flashlights. They can light up objects that are quite far away.
Advantages Over Traditional Flashlights
LED torches are more efficient than traditional torches. In traditional bulbs, a lot of heat is generated along with light. As a result the filament of the bulb gets heated easily and generally burns out in a short span of time.
On the other hand, in the LED flashlights, very little heat is generated. As a result they do not get heated up quite easily and thus have a longer life span.
The battery life of a traditional flashlight is very short. This is because in traditional flashlights a lot of heat is generated along with light. This obviously consumes a lot of energy.
Mini LED flashlights, on the other hand, do not generate that much heat. The power of the battery is used to produce light and not heat. Thus you get to enjoy longer battery life also.
Another difference and advantage of a LED flashlight over traditional flashlight is the quality of light that it emits.
The light that a LED flashlight emits is brighter than the light emitted by a traditional flashlight. Moreover, your eyes do not have to readjust to darkness when you turn on your LED flashlight. When we turn on a traditional flashlight, on the other hand, our eyes have to first adjust to the darkness. We can see in the dark as soon as we turn on the LED flashlight.
The best part about LED flashlights is that they are very hardy. You can drop your LED flashlight from several feet above the ground and still find it running. Since they are very hardy, they are very good for outdoor activities.
You can also find LED flashlights that have a buoyant body. In other words, this flashlight will stay afloat in water. So now you do not have to worry about dropping your flashlight in water.
LED torches are not only hardy and water proof, they also come in different shapes and sizes. From mini to large flashlights, you can easily find one that you need in a hardware store.
Solar Flashlights
If you find using batteries inconvenient, then you can go for a solar powered LED flashlight. These solar LED flashlights are easily available. These flashlights use solar energy. They are easy to use and are easily rechargeable. They are ideal for camping, hiking and other outdoor activities.
Though LED torches themselves do not cost much in terms of batteries, solar LED lanterns completely do away with batteries. Just remember to recharge the lanterns regularly and you would not have to worry about batteries any more.
Features You Need To Consider
LED flashlights are easy to find nowadays. They can be bought online and also in a regular brick and mortar store. They come with the following features, which you would need to consider when buying one:
• Many flashlights come with flashing feature, which will help you attract attention in emergency.
• The focusing head feature allows user to adjust the length of the beam.
• Many flashlights are equipped with regulated voltage or power. This means that the brightness will remain constant irrespective of whether the batteries have low or high power. Remember how the traditional flashlight starts to lose brightness when the battery is low on power.
• Safety switch feature prevents the flashlight from being turned on accidentally and thus draining the battery.
• Many flashlights are equipped with red LED, which protects the user’s eyes in darkness.
• They have a waterproof body.
• Buoyant body that will prevent it from sinking in water. The size of a flashlight that is buoyant is usually larger than ones that are not buoyant.
• Many flashlights come with flat sides. This prevents the flashlight from rolling over when you put it on an even surface.
• You can also opt to buy a flashlight with a hole, which allows you to attach a lanyard.
These are just some of the features that you would need to consider when shopping for a LED flashlight. Brightness is another factor that you would need to consider. But for that, you would first need to consider the purpose for which you need the flashlight. For example, if you need a flashlight for outdoor, then it is best to opt for a flashlight with higher lumens.
Buy a LED flashlight only after careful consideration of the features and you will be happy with your flashlight for a long time. Visit us at http://www.ledlightbulbsbyblv.com
