Several night dives with one set of batteries - SLX review by Heather
My husband and I just returned from a 2 week liveaboard trip where we used our SLX LED lights daily and on several night dives. Not only did we only use 1 set of batteries the entire trip, but the lights are simply the BEST for night diving. We were fascinated by the different colors of lights on our night dives, ranging from green to yellow to blue to bright white. Ours were bright white and the beam output was perfect for night diving. The lights gave us a bright focus area that cut through the darkness like a hot knife through butter, and a broad diffused area that we could use for photography.
