Review on 🌊 Suptig High Power Dimmable Waterproof LED Video Diving Light - Fill Night Light for Underwater Diving, Waterproof up to 147ft (45m) - Compatible with GoPro Hero 6/5/5S/4/4S/3+, SJCAM SJ4000/SJ5000, YI Action by James Dominick

Not very suitable for diving. Took this for a Key Largo dive and turned it on at about 35ft. It worked fine. When I tried to turn it off, it wouldn't turn off. Back on the boat I got the battery out, made sure the cabin was dry and charged it. Turned it back on on the 2nd dive and everything was fine until I tried turning it off. Again it didn't turn off until I took out the battery. My switch didn't work. Tried again after 2 months when it should have dried completely. The same, it turns on, blinds you and does not turn off. Update: I took it apart to see if I can fix it. It's not the switch that failed. Water may have entered through a switch and flooded the chain.
