With an aggressive bezel and simple user interface， the M18 Striker is the ultimate self-defense flashlight. Depressing the clicky tailcap switch instantly blasts 800 lumens with either momentary or constant on. And because the highest output always comes on first， there is no room for error when you want to access the highest output to stop any assailant in his tracks. An 800-lumen strobe paired with the 1/4 inch stainless steel strike bezel offer last-resort defensive options for your protection. If you need a lower-lumen output for a non-defensive scenario， a 150-lumen output is also available. Powered by two CR123As， two RCR123As or a single 18650， the M18 Striker is perfect for being concealed or every day carry to keep you safe in any situation.
