The lamp has initially quite a "Wow!" Effect caused. The luminous intensity is amazing, even too good for a night dive, as it floats like on a lighted highway :) You can see the strength but turn down, albeit cumbersome. The lamp has a rotary switch, which unfortunately can not use as a dimmer, but the lamp constantly to have to turn off until the correct brightness is set. One does not need the lamp and want to conserve battery life, the game starts over again, because if you the luminosity, the lamp is switched on again otherwise ..... annoying. The lamp has the luminous intensity to obtain a thick battery case, which is necessary also upright. This battery is also necessary, because after about an hour it's over with the cargo. The lamp should be used under any circumstances in the dry, because the LEDs can be quite warm and could overheat the lamp. For better or worse, what is most important in a dive light? Right! The need to remain tight. And just so there would be a problem, because after about 10 dives with a dive in caves 25m is in the lamp suddenly broken in water and the lights went out. That should not have happened, and certainly not after 10 dives.
Conclusion: + Extremely bright - Short battery life (no wonder with the plus point) - Very quickly become leaky
