Agreed. The lights favored by cave divers are complete overkill for rec dives unless you are diving in areas with very low viz. I have a pair of the type of lights recommended by
@inquisit and I rarely use the max brightness setting in tropical water. It's too bright and scares the fish away.
Something like these are great (same manufacturer, slightly different setups). Even the cave divers will use them as a final backup.
