Initially ridiculed critical of other diving athletes, I could not only convince me at several night dives from the light quantity completely sufficient. The illuminated area is indeed at an angle small but adequate, the brightness and range thanks to the special lens but grandiose and expensive Halogen Torches mostly in the "shadow" stellend. The housing is robust enough, from a spray cap + elastic band I made a cap, so that "ground contact" does not equal damage / scratches on the light emission (especially over water ...). A battery pack (4xAA) lasts much longer than the air supply and cost you by providers under one Euro. 10 dives in the Mediterranean part deeper than 30m were as easily as about 30 fresh water dives, the light well enough during the day for gaps and holes, it has become under the water is a constant companion of my buddies.
