Buy a LED Flashlight Online - Streamlight, Surefire, Dorcy

Updated on August 15, 2009

Why Choose a LED Flashlight?

Traditional flashlights use an incandescent bulb that produces a lot of heat when it is illuminated. This heat is wasted energy and causes an unnecessary drain on the batteries. Not only this, but the heat eventually causes the bulb to burn out and need replacing.

LED flashlights use Light Emitting Diodes to prduce the light. They waste much less energy on heat production and are extremely durable. This makes LEDs perfect for flashlights as battery life is one of the most important factors.

At lower power levels LEDs have a significant power advantage over traditional bulbs, however this advantage does diminish at higher levels of output as LEDs begin to produce more heat.

A Typical LED Flashlight

Flashlight Reliability

For a flashlight to be useful it needs to reliably workevery time. This means it needs power and a functioning bulb. These are both key characteristics of LED flashlights.

Energy consumption can be as low as 10% that of incandescent bulbs and as they don't contain a fragile filament, LED Flashlights can generally be dropped without harming them.

In testing, LEDs have continued to provide light after 10 years of continuous activation. It is uncommon for LEDs to need replacing.

Features of LED Flashlights

Although the first commercial LED Flashlights only appeared in 2001, today there are models with all of the features available in traditional flashlights.

Battery options include the usual alkaline and lithium, plus the rechargeable NiMH and Lithium Ion.

They come in the normal handheld design but LEDs are now commonly used in headlamps for outdoor use where the longer battery life is very important.
