I've owned several of the Underwater Kinetics 2L lights for many years, going back to when they were marketed through Buck knifes. For the size, weight, and cost, there's no other light in it's class. It puts out about the same amount of light as a 3D Maglite, in a very small package. I've gone through several lamp/reflector assemblies, and I keep several on hand. Of all the lamps, only one had a poor beam, IMHO. Mine all have a nice spot light, with good reach, and a ring around it; the price for having a smooth reflector. But given the cost of these little lights, about $26 at brighhtguy.com, and the fact that the lamp/reflector costs about a 1/3 as much as a SureFire ($6.50) lamp, it's hard to beat this light for value. I've carried the same one in my front jeans pocket for around 8 or 9 years now, and although the name is practically worn off of the plastic body, the light still works great. I'd rank this light in a 'top ten list' of the best flashlights on the market today, for the reasons I've cited. No, it's not a SureFire, but it's half the cost, or less, with 3 to 4 times the battery life. It's light in weight, and extremely tough. All in all, an excellent light in a small, economical package.
