The laser is equipped with a lightweight aluminum body, a unique locking switch that allows constant on/off, and lithium-ion batteries (20 hr battery life non-rechargeable). We redesigned some of our popular tips for this model. It comes with the Laserlift Safety Tips, Laser Line Generators, and 3 CR123 batteries. Optional accessories are a travel case, holster, wristlet, and/or lanyard, sold separately. **All our lasers are tested during final assembly at the manufacturer by industrial testing methods, then calibrated and retested to validate each laser as a “plus” 4.0-5.0mW power output certification.
