ORCATORCH D530 cold white 5000K SOS is a must-have primary scuba diver lamp. Its 1500 lumen output and 8-degree super focus beam angle provide a concentrated long beam shot. The light uses a titanium alloy side switch that offers 2 lighting modes, the high mode of 1500 lumens and the low mode of 380 lumens, which allows for easy operation underwater. The LED indicator light located on the switch button also lets you know the battery's remaining charge.
