That's a different light altogether. Yours is a clone of this U80. Even it being a clone of the U80 means very little as totally different drivers may be being used.
What would really help is a picture of the pill in your KeyGos, either separate from the light or in the light with the pic being taken from the battery end - and - can you let us know does it have a glass lens & aluminum reflector?
If the pill is good and its glass and alu then its a v.good buy for the rice. Even if the driver is not brilliant that's cheap enough to replace.
The U80 has a PWM of 500Hz, just for info. It is the fastest of all my budget chinese lights. And besides the U80 has really good built, HA, anodized threads which are super smooth when you screw on the tailcap etc. It is definitely 1 level above my Sky Ray SR3800 if you look at the cutting/detailing.
The Sky Ray 818 that I purchased from Manafont was only ~$57 and it absolutely blows everything else that I own out of the water (and I own a large number of $200+ lights). It lights a room like a 60W light bulb!
Well since this thread was necroed, nowdays the triple XM-Ls are the best bang for the buck. For 50 to 70 bucks, you can crank out 1500ish lumens. Not bad!
