Simply put, LED LENSER flashlights and headlamps use light output more efficiently than any other lights on the market. This means when you compare an LED LENSER light with one of equal lumens from a competitor (both ANSI-certified), the LED LENSER light will actually appear brighter. We achieve this through a lens/reflector optic called the Advanced Focus System (AFS). LED LENSER lights are the only products to use AFS in the world.
In addition to our patented AFS, some of the other reasons we think you'll find LED LENSER to be the best lights you can buy are:
Common Battery
Sizes - Our lights are powerful, but they don't require
expensive, hard-to-find batteries to run. Advanced Circuitry
and Cooling - Our systems allow for extremely long run
times for high-output that doesn't overpower (heat) the LED chip.
Materials - We use optimal materials for
the intended use of the light, such as anodized aluminum for the body of
our work lamps and polycarbonate for those that might see extreme
temperature ranges. Our contacts are made of gold, which is the most
effective and quality material for conductivity. Modular
Construction - With our modular
system, the light can be repaired or replaced in sections as
needed, making it easier, faster, and better for the environment. 
One-handed
Focus - With Rapid
Focus, you can go from reading to searching by using just the
thumb on your holding hand to simply slide the bezel away from
you. One of a Kind
Charging Systems - Our Floating Charge
System allows you to simply mount the recharging system on the
wall and plug it in. When you're ready to recharge your
flashlight, just touch the end-cap to the floating charge magnet and
walk away. You also have a USB option to charge from your
laptop, car, or hotel room USB port. 
At
LED LENSER USA, we take extraordinary measures so your LED LENSER light
will give you many years of dependable service. If it doesn't,
we will gladly repair or replace it, at our discretion, with one of
equal or greater value under our 5-year guarantee. Visit the
warranty page to learn how
easy it is to get Warranty service.
Our
products are sold in many countries around the world. Please
visit the LED LENSER International
website to locate authorized distributors. These
distributors can help you find retailers in your area and/or help you
with a warranty issue.
We
do not send out replacement parts for our lights, but you can visit the
warranty
page to see how to turn your flashlight or headlamp in for
repair.
LED LENSER'S warranty does not cover damages from battery leakage. However, many of the brand name batter manufacturers do warrant their batteries and the devices powered by them.
This is the unique serial number marked on each LED LENSER light at the time of manufacturing.
LED
LENSER lights are measured in lumens. LED LENSER USA uses
ANSI/FL1
standards
as published by the National
Electrical Manufacturers Association (NEMA). To date, this is the only
industry-wide, agreed-upon standard of measurement.
Polymethyl metacrylate (PMMA). PMMA is a transparent thermoplastic, often used as a light
or shatter-resistant alternative to glass.
We use T6016 aluminum as our casing material for most LED LENSER flashlights.
LED LENSER'S aluminum casings are anodized (type II, 20 micron thickness) to apply a corrosion and wear resistant coating.
LED LENSER'S electrical contacts are hard gold plated. Gold is a superior conductor and resists corrosion.
Yes,
disposable lithium AA and AAA batteries batteries can be used in LED
LENSER lights. Disposable lithium batteries can optimize
battery life (especially in cold conditions), and reduce weight.
Currently
LED LENSER'S standard lights and headlamps are optimized for use with
disposable batteries and the components can be damaged by the use of
anything other than the recommended battery type. Similarly, each LED
LENSER rechargeable flashlight and headlamp requires a specific battery to operate
and should only be recharged directly through their recharging
system.
Sometimes. Some
lights (the M7R, H7R and P5R, for
example) use the same wall plug transformer (5V, 1A
output). The H14R uses a different wall plug transformer
(9V, 560 mA output).
