Is the UltraFire HD2010 600 or 1300 or 390 lumens?
When I google UltraFire HD2010 I some sites advertizing 600 lumens and another sites 1300 lumens and also 390 lumens. Are these the same Ultrafire HD2010s, ignoring color, but using different drivers? Or are they different because of the battery being used (protected/unprotected)?
Those are all the HD2010. Its just www retailers copy-pasting whatever description they can find. I think its somewhere in the 750-900 lumen range. Its slightly brighter than the stanley fatmax on a ceiling bounce and a member on the other forum measured his stanley around 750 Lumens in his sphere.
Actually, now that I think about it, I'm not sure why either but it did come with an o-ring around the pill so, had to report it. It was very thin so I replaced it.
Why would they put an o-ring there? Seems like that would hamper heat trasfer a bit, if anything.
Good question, mine had that too. I dont think it serves any purpose… “maybe” its a way to help snug everything up if a run of lights has a bad tolerance stackup that doesn’t add up?
TangsFire from DD, for <$34. Someone said that, but, if I remember well, drivers were absolutely identical Quite strange.
Does someone have 15% off for TMart?
Yes they are all the same component wise same driver emitter etc… The Internationale Outdoor one had a darker grey color that I liked better than the light gray Tmart one but the Black one looks best in my opinion.
It’s the T-Mart one. I just popped a fresh Rev Jim’s 18650 into it and got 3.25A with no compression and 3.8A when I pushed it down and compressed the spring.
I tested mine again in stock configuration last night and came up with pretty much the same results. Before from memory it would only pull 2.7 amps. This was from a Tangsfire version. At 2.8 amps this thing still rocks.
I ordered these from MF hoping for a nicer action switch and to my surprise the switch on the board is identical to the standard switch. The only difference is the board is a slightly bigger diameter which can be filed down no problem and the spring is slightly different which should also not cause any problems.
