There have been at least two discussions on the DarkOps light, and I've posted in both with my opinion so I'll provide a shorter version of it here.
1) The light is not worth the price. For the price, there are several other lights which do the same thing better. Some are cheaper.
2) I base opinion 1 on the appearance of the light, it's specifications, and the DarkOps line of "knives" that they pinch out. The folders are blatant ripoffs of an Italian company called Extrema Ratio, and do not share the same high quality while demanding a high price. The fixed blades are no better.
3) DarkOps is neither a knife company nor a flashlight company. It is a moneymaking tool formed by Pyramont, a marketing service. The advertising for the knives is insulting to knife users and enthusiasts, and contains enough BS to make me doubt anything they say about their light(s). All products seem aimed towards Mall Ninja and armchair commandos everywhere. I'd hate to see a genuine knife or light user/enthusiast buy a DarkOps product because they didn't know any of this.
