The best thrower I've got off dx is my Ultrafire HS-802. It's got massive heatsinking and running it direct drive easily lets me push 1.6 amps through it's R2 led. It definitely outthrows my dx recoil light which is regarded as a very good thrower by others but is simply blown away by the HS-802 even in stock form when running 1 amp, at 1.6 it's definitely pushing out serious lumens and the tightest beam of all my flashlights.
To show how tight the beam is here's a shot of it compared to my c78, the recoil light has about a similar beam width at this distance too. The c78 is a very good throwing light but at 30 feet distance you can see the square beam is already nearly 3 feet wide whereas the HS-802 is only about a foot wide, maybe 18 inches if you count the corona of the beam but I don't since at longer distances the corona pretty much disappears and all that's left is a still very tight solid beam.
Also the HS-802 is significantly brighter, both of these are at full charge. The HS-802 has probably the tightest beam I've seen in a flashlight and that's including more expensive throwers that I've handled yes including the deree DBS, it's practically a perfectly parallel beam shooting out to forever, yes even the DBS diverges more albeit only a tiny smidgen more I'd say the difference is only about 6"-12" at 100 feet it's really hard to tell at those distances but there is a slightly perceptible difference. Though I do have to admit the DBS puts out more light with it's R2 module than the stock R2 of the HS-802 probably a more efficient driver, but mine with direct drive I know is pushing serious lumens. And you can easily see the beam in the air at night. Modding mine to direct drive also is pushing the led beyond it's recommended spec but I don't plan to run it continuously all the time even though even at 30 minutes runtime the flashlight is only slightly warm to the touch, and I know it's cooling the led because it never turns angry blue or shifts it's tint when running 1.6 amps.
I can't fault the construction either, smooth anodized threads on the two mode tailcap, very solid heatsinking, smooth beam profile for an smo reflector not too much ringiness and you don't even see it when in use outdoors.
