The LED Lenser Xtreme Series X21 produces a powerful 1000 lumens of lighting (or stopping) power, from seven ultra-bright, high-performance LED chips and seven terminator lenses. This blazing light makes even car headlights look dull in comparison. The X21 offers a broad circular beam as well as a sharply-focused searchlight beam that reaches up to 1500 feet. The LED Lenser X21 is one of those true feats of engineering and design that you have to hold to appreciate its impressive power and authority.
The X21 features the Advanced Focus System (AFS) technology allows the user to choose long range capabilities, or an up-close-reading flood that doesn't tire the eye. The Dynamic Switch allows for quick selection of the two brightness levels.

LED Lenser was founded in 1994 by twin brothers Rainer and Harald Opolka in their garage in Germany. Now LED Lenser has over 1000 employees, hundreds of patents and numerous design awards. There are a number of reasons to buy an LED Lenser flashlight, but one very good reason is that they stand behind their product with a five-year-warranty, wherein they will repair or replace the product and ship it back to you at their expense.
