DIY S4™ Host Assembly, Unmarked Summary

Our exclusive S4 host assembly (unmarked) is black anodized aluminum and features a tapered strike bezel-style crown/retaining ring, heat sink o-ring, a knurled and grooved heat sink holder, battery holder with cooling fins and groove detail, and an enlarged knurled, grooved and scalloped tail cap with a recessed green GITD 'clicky' switch and wrist strap. The design of the tail cap and wrist strap retention method permits the S4 host to tail stand. Also includes your choice of driver pill, brass ring, your choice of heat sink with set screw and a 0.050' Allen wrench.

The brass ring is designed to fit 16.8mm diameter round driver circuits. All heat sinks are machined to fit a standard 12mm diameter diode module. Does not come with LED diode, driver circuit, focusing ring or other related components. Can be used with our driver & pill modules or flashlight parts bundles, or in your own custom build. Designed for use with two rechargeable RCR123A or disposable CR123A batteries, or one 18650 battery depending on diode and driver used. Two 18650 batteries may be used with our battery extension tube accessory.

The S4 host is compatible with the battery extension tube, pressure pad switch, the Survival Laser holster and other parts and accessories.

Note: Blue anodized aluminum heat sink option shown in photos.
