This torch really is 'the daddy' of all torches. Here is what LED Lenser say for themselves about this fantastic bit of kit:

This masterpiece is another milestone in our company history. The LED LENSER® X21 will cause a sensation because it allows for a whole range of new applications in light engineering. The lamp has a light output of up to 950 lumens*. Thanks to the Advanced Focus System, the light cone can be adjusted dynamically.

You must have held this lamp in your hand to be able to really appreciate it. The LED LENSER® X21 offers a broad, circular low beam as well as a sharply focused searchlight beam. 7 ultra-bright high-performance chips and 7 terminator lenses produce a quality of light that you have never experienced before - a blazing beam that makes even car headlights look pale in comparison. This lamp’s lighting range is already legendary. And its impressive appearance radiates power and authority.
