The silver Gamma LED Dive Light from Ikelite has a double O-ring seal and a depth rating of 400'. Its single LED outputs over 220 lumens at a beam angle of 10° and a color temperature of about 6500K, and will burn for up to 10 hr. The mechanical tail switch allows you to toggle between continuous and momentary lighting modes with ease.
The body of the Gamma is constructed from aircraft-grade aluminum, which has been anodized up to military specifications to safeguard against the corrosive effects of seawater. Despite this durable design, the light weighs a mere 4 oz. An ergonomic, no-slip contoured grip gives you a secure hold while allowing you to slide the Gamma in and out of a pocket without any hassle.
Optional flashlight mounts for 1" ball systems and 1/2" or 3/4" flex arm components enable you to attach the Gamma to the lighting arm of an underwater camera housing and tray system. Additionally, the optional Diffuser M27 threads onto the front of the Gamma to widen and diffuse its beam, changing the angle of coverage to approximately 30°.
This dive light is powered by 2 included CR123 batteries. Also supplied is a wrist lanyard with cord lock. The Gamma is designed, built by hand and tested in the USA.
