As a Ground & Sea SAR member for 10+ years, many i know of there used various models, but seem to like the ones with built in charging and ran from a single 18650. some reliable ones i seen used, ( and used myself) as above is the Zebralight H600w, Nitecore HC50 & HC60, and similar models. There are a few good AA & AAA powered models out there if you prefer standard battery power sources, as in various Petzl models including the Tactikka RGB variant. Though in my case most all my headlamps i modified with better tints and options as i do with most of my lights.
