Bought this driver http://www.lightmalls.com/8-4v-3000mah-5-mode-led-flashlight-circuit-board-led-flashlight-driver-for-3xcree-xm-l-t6-or-5xcree-xm-l-t6 as a replacement for sky ray 3800 rev.2,which had burned out.It was sort of an impulse buy because I wanted to fix the light for some time and I didn't want my sky ray king to be lonely on the way here.Overall,it's output is disappointing and nowhere near the 3a claim in the specs.Tests were done with 2 redilast 3100 mah,fully charged to 4.2 volts.Results as follows,high-1.94a med-1.20a low-.54a.Needless to say,my sky ray king absolutely spanks this light,but at least it works now.PWM is not apparent on high and medium but low is very noticeable.Strobe is fast and I think the medium is waaaayyy too close to high mode and low you can almost look at the emitters without squinting.I can't see this driver being used for a 5x xml light let alone the triple,like they recommend on the product description.BOTTOM LINE anyone thinking about this driver should just pass on it,very under spec from the description and PWM is really noticeable.
Is 1.94A the tailcap current or current passed thru LEDs?
By the way, if you still are in need of good driver, take this one: http://www.kaidomain.com/product/details.S020121
I use it in my modded FF STL-V2 and it pulls 2.4A from 4*18650's (LiFePO4 ones), that's 32W, even more than claimed power of 30W.
Thanks for the advice.
I'd have passed anyway when the driver says it has 3000mAh capacity 
.
@shadow that is the tailcap current and I may just give this light to my son but thanks for the driver suggestion.@pulsar-I had a laugh at the 3000 mah crap too,I should have known better!
Thanks DARCANGEL. Good info.
No prob,I hate to sound like "mister negative" but it is what it is!
Huh? 2A at tailcap with 2 cells in series are about 16W. So should be at least 10W to the LED..
This driver is for 3 LEDs in series (and that’s how OP uses it). So while it claims 3A per LED, it essentially can do max. 1.5A per LED.
Oh, 3 in series.. makes sense then. I only thought of parallel.
Have you checked if later as the voltage drops the current increases, It should since the input voltage is 8.4v only. It might be a possibility that the manufacturer has specified the max current the driver can possibly achieve, as in when it has to boost the voltage harder?
It doesn't claim 3A per LED, it only says 3000mAh max current with no other specifications.
