Sorry I'm only 17 and I'm a beginner at electronics, if even. If you could tell how to measure the Amps I may be able to do it. I ones of those Digi multimeter things that might be the tool to do it.
I got 3.18 Amps on these with a rev jim unprotected panasonic ..More than my 980L and keygo ke5 .. not much more ...but more . the med is pretty low and i like the 3 mode ...(sorta)..only one obnoxious flashy to pass by.E1320 says the driver is a cheap one that Kaidomain uses too(unverified) tint and beam quality isn't perfect butnot bad .. I've seen worse for much more money .at this price it's a gift..You can add a battery and charger and still be under 20$ .. pretty amazing to me.
I think you did it right. The results can vary with the battery as well as the driver; I don't know if that would account for the difference between your result and that of Boaz or not.
I was using a red Ultrafire 3000mAh PROTECTED battery.
On my second attempt my test results are around the same still, 1.7 amps. I set the multimeter to the settings that shows "A" then 3 dots under a line and the 20m.
Ok a couple shots of the driver (as far as I'm willing to take it apart because there is always a 50/50 chance of me breaking something when I take things too far apart).
If you need a different angle or the Driver to be pulled apart more, your going to have to give me instructions because i'm not sure how.

Seems like there is some small particles in that XM-L emitter dome. Not scared of them for this price though, DX has had them in every XM-L cheap´o headlamp I´ve ordered to my friends.
