Really? Hmmm @ bad review posted - this is an AMAZING light for the price, GOOD QUALITY to boot - I have 2 of them, one for my Adams Arms AR15 and one for my VEPR12 and getting ready to order a 3rd to give to my son - 800lumens guys, yeah 800 - pretty darn bright and the strobe is KA - and of course you have med and low power settings - if you're smart, you'll buy this also to compliment the light for rapid lights on effect/control: Mako T-Grip Integrated Foregrip & Tactical Light Holders (copy/paste item description), this is sold by the same seller at their website - best device ever for quick/rapid lights on effect, I absolutely love this device and the Nightstick works perfectly in this holder - best combination light/holder ever conceived. Don't hesitate buy the nightstick and the FAB Defense/Mako - for an extra $79. or so, you'll be really really glad you did (Amazon does have the Mako avail. in Flat Dark Earth Tan here, for other colors, etc follow my tip above, Amazon link here: http://www.amazon.com/Ergonomic-Flashlight-Activation-Ultimate-Silicone/dp/B00K8F3S6A/ref=sr_1_fkmr3_3?ie=UTF8&qid=1419467650&sr=8-3-fkmr3&keywords=Mako+T-Grip+Integrated+Foregrip+%26+Tactical+Light+Holders
