All I buy are AceBeam lights. They have a very wide selection to choose from. Very well made and lots of accessories. Nice carry case, lanyard, usb charging cable, o-rings and a 21700 5100mAh battery. I bought the 6000k because I wanted the brightest light. 4,000 lumens with the Cree XHP70.2 chip. They claim 373 meters but the farthest I used it was around 500’. The beam is wide about 25’ but the Cree XHP70.2 punched out further. For myself 500’ was perfect distance. 200’ was very bright. The modes are firefly, low, mid, high, turbo and strobe. One click on the tail switch is turbo. It’s 6” long, well weighted and fits in hand and pocket perfect. Hopefully my thoughts on this light answered any questions you might have on this light. I would definitely buy this light again. I always order from kill zone flashlights. They have what I need in stock, their prices are better and they have very fast shipping.
