18A is the teorethical total if all emitters were parallel driven. But don't really think it's driven this way.
9 emitters is an odd number. The easier way to drive them all would be 3 parallel groups of 3 series emitters each. This way a driver for 3 emitters could be used, and the total amp draw from the cells would be 6A.
Well, 6A is a big number anyway, I personally would not trust 18650 cells in this application, unless IMR. For decent 26650 it's all good.
Curious to hear about real world beamshot comparison. The 3 center emitters, with those extrasmall reflectors, would add to the total lumens output but the throw increment would be marginal.
I just pulled the trigger on a Sky Ray King and I was seeing how this is compared to it. I also want to know about how long this will stay on high. If this is as bright as I hope, imagine what the strobe is like
after reading this post, it definetly gets my attention now! i was pretty close to buying the x100, but this clearly should be brighter with even more flood.
so im thinking the tk70 still outthrows this sky ray correct?
if i was shining at a tree…say 150 feet away, will the skyray or tk 70 be brighter?
hello rick,
can you guys offer this light in a light, batteries, and charger combo for 26650 cells.
i dont have any 26650 cells and a charger at the moment, and that would gather my interest even more in purchasing this light.
The TK70 definitely out throws the Sky Ray. The reflector of the TK70 is much bigger as are the cut-outs in the reflector. This is definitely a flooder NOT a thrower but it out floods MUCH more expensive lights. And heat is much better dealt with than in my Dry for example.
Sky Ray 9 XM-L is about 3200 lumens OTF. Same ballpark as the Trustfire X100 in OTF lumens. The TF X100 would out throw the Sky Ray by a wee bit.
You could gun the Sky Ray at > 3k lumens OTF for 2 hours with 2 sets of 26650 and it would not feel any pinch.
The good thing about this light is that it probably can operate in 2S mode with 2 x 26650, but for short periods only like 30 mins coz the TF 26650 protection trips at about 6.5 amps. The TF X100 is a 3S light, and the tubes are not interchangeable with the J12/J18 series. (would be good if it does, but nope the threads are totally different)
cant wait for some beam shots or just some comparison chatter. id like to know if it throws further and does or does not have a floodier beam/spill than the j12, and the king, dry, or tm11.
if floodier, can this be one of the floodiest lights available then?
Just extrapolate it. Just take TK70 to be ~ 2200 lumens OTF. It could be 2100, could be 2300 as well, don’t know. But seriously that’s ok and definitely much more accurate than a DMM current measurement which has even more + bigger variables.
Aaaah I see. You should note that the TK70 is claimed at around 2300 but has never been tested. The TN30 has been tested, although by home made setups, to be around 2700 lumens. Hence my estimate of around 4000 lumens for the Sky Ray. I’ve ceiling bounce tested heaps of lights of various sizes, about 30, and it fits my testing more accurately to say the TK70 over produces than the TN30 only give 2300 lumens. When I say fits I mean comparing all the tests to factory claimed lumens(non chinese ), and tests on CPF. I’d love to see one of the “professional” testers on here or CPF get their hands on this one.
