Put mine thru it paces last night.
Out did the DRY easy, although mine isn’t the Turbo model, the one before.
Will compare to the Spark, TJ-12 and TM11 tonight.
Heaps of light out of this girl, and does throw easily for 150 metres with heaps of white at the other end.
My Dry is the Turbo. I wouldn’t put the TM11 in that test tonight. It’s a lovely little light and you’ll hurt it’s feelings up against this bad boy. 
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)
Next step, someone mod it with a $20 KD driver.
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?
How did you test it?
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.
Can’t be the floodiest, there are stuff like the Xeno E03.
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.
Me too
Actually there have been several verifications of the TK70 to be correct for the OTF lumens. Just that the lux reading by Fenix is a bit on the high side.
I am also basing this with my collection of nearly 100 lights.
Don’t have to be CPF only for the sole source of information, but from german/russian forums as well.
PS. Don’t have to be worried about the lumens definition, that is why we always use “OTF” which means Out-The-Front. All standardised already.
You are saying that the TN31 is 2700 lumens OTF and 125 on your meter? / If you have another known thrower + well driven light like Crelant 7G9/Olight M3X/SWM T40CS….that’d help as well if we could have those figures.
No. 125 which is about 2875. TK70 110 which is about 2760. TM11 86 which is about 2000. SC600 35 which is 780 etc etc.
I would love to browse the german/russian sites but I only know 2 languages. English and Aussie.
Has anyone compared a TK70 to a TN30 with the same meter?
TC40CS(U2) - 41 or 943.
TN11S - 40 or 920.
Crelant 7G5V2 - 40 or 920
I was taking TK70 to be 120 as per your 1st post, so i guess that’s a bit off.
I actually had 2 TK70s, one was very slightly driven better. But very slight. But 2200 lumens OTF is more or less correct. TM11 might not be a good candidate due to the long history of the small driver quirks here and there.
If that’s the case then it might be a bit better for the Sky Ray. If we use a factor of 20, then it’s 175 x 20 = 3500. You mentioned 185 as well (initial reading?). So that’s 3700.
If we take 21 then it gets quite close to like 3900 lumens OTF. Seems possible to be a wee bit better driven than the X100.
These lights also have drivers which regulate the power a bit differently when driven with 2 cells, 3 cells and 4 cells. The J12/J18/X100 all exhibit this behaviour. The 2 cells might be a bit brighter. This has been documented in the X100 thread as well as on thaicpf.
The T40CS is quite a good candidate. Well driven + well heatsinked, stable driver. It is advertised to be 788 lumens OTF. I measured it to be in the same ballpark as well.
So seems to be factor of 20 is better.
If you have a good DMM/short leads……and TF 26650s, you can have a better idea then. I can supply my results with the TF X100.
Sorry I typed my first reply to you with figures from my head. Doh. I have since edited them. Upon reflection I agree with your figure of 20. 
Damn, you got my fingers itchy again.
I am sort of waiting for the 12 XM-L model. :party:
Given the adjustment I’m still even more confident that the Sky Ray is on the WOW side of 3500 lumens.
Yeah, most likely worst case scenario of 3500 lumens OTF. Using “OTF” is great, coz it doesn’t care how much the glass is cutting, how lousy the reflector is, driver efficiency etc.
But as always, to notice a jump in brightness, you’d need a min of 20% and that’s assuming with the same sized hotspot. So there really is not much of an upgrade from TF X100 to this Sky Ray.
Maybe you could get to a distance of say 7 metres and measure the lux? I guess you know how to convert to lux @ 1m or candelas, if not just post the RAW figure.
I don’t have anything with which I can measure the distance at the moment. How about I take some lux readings from the same spot with the Crelant, Sunwayman and Sky Ray? That way we should be able to estimate the distance given the previously tested, by you or others, lux @ 1m of the Crelant and the Sunwayman. And therefore the lux @ 1m of the Sky Ray. First I’m going to have to walk the dog though!
