Lights are RECSEA RML-18650 MINI 1000LM, 300 meters rated LED's are compact and well made with aluminum housing double o-ring seal and twist on-off controls.

 At a 1000lm the lights are powerful and reliable, using four with a video rig granted more than enough illumination, and the batteries on constantly for a 60-minute dive were still going strong despite not having time to re-charge fully between our dives. Also, great as a handheld primary their powerful beam has no "hotspots" and provides great overall coverage.
