Review on 🔦 Goldengulf Professional Scuba Diving Flashlight - 5PCS CREE L2 LED Super Bright 4800 Lumen Underwater 100M Submarine Light with Battery and Charger Included: A Comprehensive Review by Minas Chase

photos taken with no light caused flare in my camera lenses because they were so bright. Yes this is good. No, I haven't dived with it yet. I love flashlights and it's like holding a good car headlight in your hand. Big bright ray. Some splashes that illuminate the area and aren't focused enough to present a true blur. In other words, a well usable unregulated beam. Will highlight things in the block with no problem. Turning it on and off is via a slide switch, which I believe is magnetically connected to an internal switch. The only way I could think of to make it 100% waterproof is with this design. It heats up a bit with use, but doesn't cause any discomfort. I'm in Yuma, USA during the summer, so my summer overnight temperatures are higher than most of your summer daytime highs.
