The new Survival Laser S4X™ host is the big brother to our original S4™ host. This massive host accepts 2 X 18650 batteries and uses the same heat sinks and driver pill modules as our other hosts. The S4X weighs over 6 times as much as the S4 and has far greater heatsinking capability, which allows longer run times without overheating the diode. In addition, the use of two 18650 batteries more than doubles the potential total run time of any of our smaller hosts.
The S4X features a tapered strike bezel-style crown/retaining ring, a knurled and grooved heat sink holder, battery holder with cooling fins and groove detail, and a knurled, grooved and scalloped tail cap with a recessed 'clicky' switch and wrist strap. The design of the tail cap and wrist strap retention method permits the S4X host to tail stand.
Includes your choice of aluminum or copper heat sink with set screw and a 0.050' Allen wrench (or no heat sink), choice of drilled aluminum, drilled brass or heat sink driver pill to fit a 16.8mm diameter driver board, and choice of black anodized laser etched with the Survival Laser logo, or with no marking in black anodized finish.
Note: If you select the "driver heat sink" pill option, you should also select the "extended and tapered copper" heat sink option to allow enough room for the other laser components.
All heat sinks are designed to fit a standard 12mm diameter diode module.
The S4X can be used as a high performance flashlight with our flashlight parts bundles, a single 18650 battery and a dummy 18650 battery.
Note: Does not come with diode, driver circuit, focusing ring or other components. Extended and tapered copper heat sink option shown in photos.
Overall Length: 7.87" (200mm)
Maximum Diameter: 1.50" (38mm)
Weight: 358 grams (without heat sink)
Great product - Andrea - 8/14/2017
Good Things: Extremely solid. It stays well in hand. The finish is great, even on the threads those connect the pieces, the anodize is perfect. It dissipates the heat very well. Bad Things: As other hosts it has NO SAFE SWITCH, You have to make one yourself if you need it. While screwing on the bottom cap, there is some chance for the laser to fire up randomly, you have to take care even whan putting on batteries. There is no way to know if the switch is on or off, before putting on the bottom cap. In general: Very cool looking host, really satisfied by this. But take extreme care when putting on new batteries! Always wear good glasses when handling this!
GREAT HOST! - JOSE FLAVIO MARANHAO DA SILVA - 4/10/2017
