I'm sure it's brighter than the single T6 version but it might not be that much brighter. Three LEDs vs one doesn't necessarily make it any brighter. To drive three T6 LEDs as hard as they are driving the single T6 LED in the single LED light would require 3 times more current from the batteries. Can those cheap 18650's handle that??? It would also generate 3 times more heat and the single LED light wasn't exactly brilliant at exporting its heat to the outside casing. So this one could either burn out (quicker), catch fire (battery) or just not be that much brighter?

I suspect it will be have much more flood but less throw than the single LED light. Assuming it isn't actually three times brighter than the single LED light, the surface brightness of the LEDs will be lower than that of the single LED light as say 50% more lumens from 200% more surface area will result in a larger but dimmer beam profile. Also there are now three small reflectors rather than one large one and large reflectors focus the beam better.
 
The thing with that 3600lumen one is that if the LED's are driven lower would they last longer and the heat be less? Theres a UK guy selling a light and he states the same about his, could be driven harder but at the expense of the longevity.

Each LED may not be as hot but the total temp and the temp of driver board may well be higher.
