Link, please 
Stupid me. Link added.
Who do ALL of the descriptions EXCEPT on tmart’s website say: “Circuitry: Digital Regulated 2300mA Current Output”
For SURE these different websites MUST be using different drivers, or something!!!
I guess I’ll just order the black one from tmart to be sure

I sure hope she pulls 4amps at least!

When the cell voltage is higher, that causes the LED to draw higher current, which trips the protection circuit. If your cells were more depleted, or had higher internal resistance (from being old or cold), the current would be lower and the protection would not need to kick in. It’s not your light, it’s your cells. If you really want to use those cells in that light, you might be able to if you just don’t put them in hot off the charger. Put them in when their open voltage is lower (“condition them” for use this light by taking down their charge a bit in another light) and I’ll bet you find the protection doesn’t kick in and kill the circuit. You could also try adding some resistance to the circuit (oxidize the tailspring and or the threads a bit for example).
I just got the gray HD2010 from T-Mart, it pulls 4.20A on a TF 3000 flame. I tried a old blue TF 2500 and only got 2.8A —- brightness seems pretty good on either. I still need some 26650 batts, I’ll probably get the flames from M/F. The T/M 2010 is quite a thrower and T-Mart got it to NW Wa. fast.
Sweet!
My flashlight builder buddie says it’s current regulated in every mode except high, where it’s direct drive So WOOT!
I’ll order some up for the times my friends need a thrower!
For the other times, it’s the Poppas W-878 26650 zoomie
For my EDC… oh boy, just you wait!!! It’s a surprise

I liked mine from T-Mart so much I just ordered a 2nd one. Very nice light.
There are quiet a few of you guys out there that one is not enough. I just dont understand it. Some people have three and even four of the same thing. Why? Why? Why? You can only use one at a time. Do you all have more money than sense? No wonder women get so mad with there men, why do you need more than one of the same thing they ask. What do you shrug your shoulders to justify it? This is doing our reputation no good. You must all stop it now I say.
Yeah, I bought another last week to. Who cares about our reputation. Cheers all.
I probably have roughly as many lights as the Mrs. has shoes - and her shoes eventually wear out and get discarded, whereas my lights continue to serve. Conscience clear.
Hahaha, veeeery nice reply on that one, tech :bigsmile: :bigsmile:

You have a lot to answer for. My sanity for one. I still have it, thanks. I dont own a solarforce host yet but have more than a few dropins that have no home though. Is there still hope? 
We all need lots of double up on flashlights.
Edit. I have plans for the new arrival.
I accept full responsibility and offer semi-sincere apologies to flashaholics' wives everywhere. If your relationship can handle another flashlight, it can endure the worst of life's challenges.

Has anyone determined the cause of the lower current readings in their HD2010 yet? Seems to most likely be our cells, but I haven’t been able to break 4A with my TFF 18650s (less than 3A) or my Solarforce V3 2600 (3.7A). I am topping off one of each of these to try again - and my new DMM is pretty cheap - so I can’t say for sure that I am getting accurate measurements anyway.
Everyone seems to have the same East 092 driver in their HD2010, so I’m thinking it has to be the variance in all the cells out there…
Regardless, I’m still pleased as hell with this torch.
and it’s a big problem for high currents measurements. Anyway, 3.7A is a really nice current @HI.
True. If it’s an accurate measurement, I’ll get high performance with better run times with a 18650 at least, until I get my 26650s.
BUT, the detective in me still wants someone to help solve the mystery - the inconsistent current readings from so many HD2010 owners has me a bit worried about possible variation with the East 092 drivers. Sure, our 18650s are all going to be a tad different, but while TFFs (if real) and SF V3s are proven li-ions in general, they aren’t high-end 18650s. And many out there with lower amp measurements surely have a better DMM and leads than I have. Johnny Mac got 3.5A with TFFs, and Foy got 4+ with SF cells. One of them - I can’t remember who at the moment - got their HD from TMart, as did I. From what I have read, it doesn’t matter. They all have the East 092 driver.
All in all, it really doesn’t matter that much. The HD is obviously a bad ass, regardless of top current readings at the tailcap. I’m just a curious newb trying to educate myself and having a ton of fun doing it.
Thanks again to all. I love this place.
My HD is still “on the way” :bigsmile: I’ll be very happy if mine will do 3.5A with my TF black/flame 
I get 2.5-2.7A with MF UF 3 mode drop-in.
Anyway, can be dozen of things: diff batch of cells, diff batch of drivers, bad soldering, cheap DMM, cheap leads…
Hahaha! You are totally right.
What is it about us torch freaks that makes us want to push our poor little XM-L emitters to their very limits? If we’re doing a good 3.5A with an HD2010, isn’t that like 700 lumens in an XM-L T6?
If we hit closer to 900LM at near 5A with a 26650, I would hope we’d notice a difference. But really - is it useful difference? Do I really need to prove the XM-L will do the 1100LM limit it’s been tested at? No. Haha. This HD2010 doesn’t more than it needs to, and direct drive is inefficient when it comes to 5 amps anyway. I am learning that a well managed driver is more important because it also supports better run times.
It’s hilarious, because as much as I love this torch, I can’t even imagine a practical need for it to be brighter than it already is. I mean, the WOW factor and impressing my friends can be accomplished with my SF L2T, and lately the TF Mini-01.
I know that there’s so many on BLF who actually USE their lights on a regular basis for work or whatever. But it seems the addicts end up with so much more than they’ll ever use - and I already have, just in the last couple months. The HD is the pinnacle marker of this sickness. I had a few staple torches, and I needed a dedicated thrower. Didn’t I?
Match did a graph a while back that clearly showed minimal gains above around 3.5 amps for an XM-L so, you're right, this is just for fun.
Speaking of which, I just tested mine again on my Sinometer and it shoots up to 5.20 and then settles down somewhat at about 5.0 amps. (King Kong XSL) If I touch the end edge of the flashlight body with the side of the positive lead and press as gently as possible against the battery with the other, I can get it to read 4.80. What a monster.

Hmmm….
Thinking of getting to 26650 train.
Seems like a good replacement for a 2 x 18650 thrower without giving up all runtime.
