I have one of these I got cheap - League | Princeton Tec
Just a basic underwater flashlight. Uses 4xAA battery and great for looking in crevices for Octopus etc. I have used it on night dives, but it does not turn night into day. I get about 8 hours before I feel new batteries make enough brightness difference to change them.
