The Survival Laser II Special Edition specs out at 2.2W (2,200mW) +/- 100mW peak optical output power at 445nm wavelength with the included high-efficiency G-2 lens.

The SL-002SEPBAR laser includes your choice of standard C6 or Survival Laser S4™black anodized aluminum host assembly with extended solid copper heat sink, (P/N SL-SLS4LHA), or Survival Laser Stainless Steel Host Assembly with extended and tapered copper copper heat sink (P/N SL-SLSS2LHA), solid copper diode module, 1.8A diode driver circuit with silicone insulated leads, G-2 lens assembly, external lens spring, silicone lens cap, a blue anodized extended focusing ring, a syringe of Arctic Silver™ Ceramique 2 high-performance thermal compound, two RCR123A rechargeable batteries, a dual RCR123A battery charger, a laser holster, a set of Eagle Pair OD4+ 190-540nm goggles (your choice of standard or slip over styles), and an 18650 battery extension tube. 

The Survival Laser II Special Edition incorporates the same modular, "no soldering required" basic design as the other Survival Lasers.

Only the best 445nm laser diodes will meet the optical power specification of the SL II SE. Each diode is hand selected and bench tested with a LaserBee II laser power meter for acceptable power output at the design current level, and is tested once again after being assembled with the actual driver circuit.

A "total heatsinking solution" was designed for the Survival Laser II SE. This was especially important given the high output power of the diode and the small size of the laser host. A new extended copper heat sink was paired with a solid copper diode module and Arctic Silver™ Céramique 2 thermal compound to effectively transform the entire laser host into a heat sink.

Our blue anodized extended focusing ring is supplied with the bundle to allow for easier and more precise focusing without burning your fingers. The blue focusing ring and extended copper heat sink profile gives the SL II  SE a very unique and distinctive appearance.

The Survival Laser II SE operates for up to 30 minutes total time per charge with RCR123A rechargeable batteries, and can also use two larger 18650 batteries with the included 18650 battery extension tube to achieve longer total run times. The recommended duty cycle for the SL II SE is one minute on followed by two minutes off.

The goggles supplied with the SL II SE bundle are adequate for use when looking at the spot created by the assembled laser on a non-reflective surface. However, NEVER look directly into any laser beam or its reflection even when wearing these goggles. Note: These goggles are for personal use only, not for any commercial use that is regulated by OSHA.
