Extremely durable and long lasting. I have had 2 or 3 of these lights for sevral years with hundreds of dives with them all over Alaska in everything feom -40f ice diving to 180' tecnical dives these lights have never let me down. The light itself is a little dim but for cave or wreck it is more than enough. I have used mine multiple time for full night dives without isue. The beam has enough of a hot spot that signaling and communication is not a problem. Overall im very happy with the light.

Totally confident in these as backup lights for cave diving. A well proven, reliable, and very robust design.

Super light! great for a starter light and super bright, well constructed, I eventually moved this to my backup light and then bought another. I love the fact that I can use c batteries and not have to wait for a recharge.

very bad backup light! the body construction isn’t enough strenght ( cheap plastic) and the light isn’t powerfull .Sorry but for the price I expect muche more.
