Sondiko 4000Lumens CREE-XHP70.2 Waterproof Diving Torch, Bright Rechargeable Scuba Dive Safety Lights 100M Underwater Flashlight with Power Display Function, Professional Submarine Light with Battery

Although the light at first appeared to be well-made, after the first dive, the light would not cycle through the different settings and the strobe feature never worked again after the first time it was used. Using the brightest setting drained the batteries very quickly, in a matter of a few minutes. After recharging the batteries, the light would not stay on the brightest setting and would only work on the lowest setting. I sent it back and received a fast refund. I do not recommend this light.
