Great tool for underwater and topside - SLX Focus Light by Saad A.
I just got an SLX focus light and WOW, that's one great tool. I even use it for my topside photography when I shoot night scenes and need to paint with light. All I need is to just put the diffuser on and I'm good to go.
Here's a shot I painted with the SLX focus light:
