Forget everything you've ever seen!
Primary backup lamp X1 and X1-VB-FFX1 - VB was the first scuba LED lamp that managed to create an adjustable beam of 3 ° to 25 ° in this light quality.
In the spot position (3 °) the light beam reaches a brightness of 17,500 lux, and thus offers a perfect signal even in the worst possible light conditions. In all settings, you have a shadow-free light.
X1 - FF for those who are "only" looking for an exceptional backup lamp can take advantage of the X1-FF. A fixed focus version with a 3 ° Spot fixed focus returns a great penetrating beam in all waters and in all situations. The brightness of the X1-FF is incredible 21,000 lux, and is thus in its performance, the brightest bulb of its type on the market.
The X1 is designed as a modular system and is available in two different battery versions: with 3 x AA cells with 3 x C cells. All components are of course interchangeable. The lamp is switched on and off with the thumb. Therefore, our switching system is completely unaffected by the increasing ambient pressure at greater depths.
By the way, when we speak of focusing ability of an LED lamp, we do not mean moving the LED from the focus of a reflector. Something like this is humbug.
We're talking about a movable optics.
