Ikelite Gamma II Waterproof Dive Light, 6500K Color Temperature, 350 Lumens, Red;

Each Gamma starts with aircraft grade aluminum, precision-machined into a supremely ergonomic, no-slip contour grip. We purposefully avoided unnecessary grooves and texturing on the light body to allow it to slide in and out of your pocket without snagging. Military-grade anodizing and a double o-ring seal provide corrosion-proof and waterproof operation up to 400ft (120m). A heavy duty mechanical tail switch provides either continuous or momentary lighting at the touch of a button. Dimensions 5.6 x 1.4 in (142 x 36 mm) Weighs only 4 oz (113 g)
