This is from my 2 tank night dive from Koloa landing boat ramp in Kauai, Jan 2023 with Dive Kauai.

I filmed this with my Sony RX100V and the lights are listed below. The spot light uses 3 2170 cells, so they were easy to swap out between dives. I rigged up a USB-C battery, USB-C PD trigger to get 20VDC and a Constant Current variable voltage power supply to charge the batteries for the flood lights.
