Niwalker Nova MM18II 8200 Lumen 4 x 18650 Flashlight


The Niwalker MM18II utilizes a total of three U.S. made Cree emitters, 2*XHP70 and 1*XM-L2. It also has a maximum output of up to 8200 ANSI lumens. The highly efficient circuit design offers maximum output and runtime. Dual Multi-function clicky side switch with momentary activation and on/off Memory function to remember last output setting used (except hidden modes). The advanced thermal protection circuit prevents overheating. Unique reflector design provides great throw, beam distance, and beam pattern. Aircraft grade aluminum, mil-spec hard anodized for maximum wear. Toughened ultra-clear tempered glass lens with anti-reflective coating. Large copper heat sink pad for superior thermal conductivity. LED indicator turns red to alert users to switch to a lower output mode and recharge batteries in time.

Very disappointed
I purchased the flashlight on 12/17/15. I used the flashlight for two weeks for work. I work as a railroad conductor. The flashlight stopped working and I have checked to see if the batteries or charger are the issue. They are not the problem. This was a $250 flashlight that lasted 2 weeks! Now to be repaired will be a 2 to 5 month process! I am very disappointed in Niwalker.
