SOONSUN 50M Underwater Diving Light Waterproof LED Video Light for GoPro Hero 12 11 10 9 8 7 6 5 4 3 Fusion Session and Other Action and DSLR Cameras

After purchasing 2 for a diving holiday, one failed after two dives with the light refusing to turn off. The remaining light worked well, but for the price, a 50% failure rate is not acceptable

This light attaches nicely to a GoPro and provides decent light in a wide angle. I took it down to 106' in a cave dive and it gave me ~1 hour of light at full brightness on 2 GoPro batteries. It charges in a couple hours via micro USB. You'd need 2 spare batteries if you were doing multiple tanks. This is no good as a primary light in a dark cave but makes a good supplemental light to improve your picture quality. I also used it at depth in a daytime reef dive to add some color to some close-up coral/fish pictures without the camera red filter.

Used it on my first night dive the other day. Was going very good. Then returning to the surface I noticed the light did not turn off. What it looks like is water got around the seal. Now the light will not go off unless the batteries is pulled.
