Ultrafire HD2010 only drawing .8 amps on high

LED Flashlights – General Info 18650 Flashlights

hello, i apologize if this has already been covered but i could not find the answer i was looking for.

I just got my HD2010 from tmart in the mail today, and it only draws .8 amps on high. I was really hoping i was going to receive the direct drive ones like so many have received.

Im looking for advice on the best thing to do about it. I guess i could send it back but i dont know if they are all like this now maybe??

I don’t really mind putting another driver in it if there is one i can easily obtain that will still give 3.5+ amps to the LED.

Lastly, could i jump around the driver and put the led in direct drive mode for a direct drive only light?? Im not worried about emitter lifespan.

Thanks for any help!

From which vendor did you buy it? FastTech’s HD2010s have been known to pull notably low amperage.

maybe you got a bad driver..0.8A High for an XML is sad.

will contact them if i am you..

Bought it from Tmart

I had the same experience with my HD2010 from tmart. I didn’t mind because I bought the light with the intention to change out the driver. DD just sounds like an emitter fry wanting to happen. I replaced it with the $3 Nanjg 105C 2.8A at Fasttech. Added 4 7135 chips. When I finally got my King Kong 26650, this light became quite impressive.

What battery and at what voltage is it that you are using?

There seems to be a batch issue with the East drivers that the HD2010 uses, I purchased a couple pf drivers from fasttech and both only put out around 1A in high mode, yet annoyingly were direct drive in those pesky SOS/strobe modes. Sounds like T-Mart has the same batch. If you know how to replace the driver that’s probably the quickest solution.

This is the driver that I found recently, as did many others. 3.04A and silent operation. Reliable, dependable, and I’m getting 2.83A at the tail off of an LiNiMnCo 26650. Very nice output with no noise at any mode position.

I bought one from FT. Same behavior… Thread about it here.
I got a free replacement (that should be good) before they went out of stock… Its now been 39 days and my package have still not arrived… (I have received 5 other packages that was shipped later from FT)

Would be nice to see a good source for these drivers…

How would add say a Qlite driver work with say 8 extra 350 chips work. Total of 5840mA. For batteries who are not capable of delivering that type of current would you basically get output close to a DD east 092 on high? But have have 25% on medium, 1460mA. And 2% on low (116mA).

Using hot off the charger 3400 panasonic 18650’s.

That looks like a pretty good alternative i may go that route, although i was really hoping for DD capability because this is purely a play light.

Interesting, do you have any idea if the ones fasttech are selling now are still low on current output??

Oh… They are back in stock… (that was not the case a few days ago).
I would expect they have manged to get the right ones now since several customers was not happy with buying a driver that should be DD but wasn’t on high… But only way to know for sure is to buy and try…

You’d hope not, this is a new batch and the ones I got were just before the old batch went out of stock. You should ask customer service at fasttech, there’s a rep there called techgeek or something or rather who knows his stuff.
