based on the shots in the HD2010 Review it will have the logo (note, review links to the same item). Many of the lights on Tmart show pics without logos, but they come with them when they arrive.
EDIT: BTW, I ordered one (as did many others), so I can update you when it comes in (ordered two days ago, hasn’t shipped yet).
Welcome to the forum.
From what I’ve seen, people get them both with and without. Tmart also has another one listed from the international warehouse that I believe is listed as TangsFire. KumaBear sells very good 26650s if you are in the US. Or if you are looking for something a little more on the budget side, TrustFires are pretty good. Right now FastTech has the best prices that I know of on those.
Will post links if needed.
I ordered one a few months ago that came with no logo. Sent it back because it was defective. The replacement they sent does have the Ultrafire logo and works fine so far.
After a few days it started flickering and occasionally wouldn’t turn on. Would also skip modes. I cleaned everything and it continued doing the same thing.
My Tmart HD2010 was defective, too. I ended up selling the host and only got $5 back from Tmart—and that after a no-reply on the first email. I’d be weary of HDs from them. Lightscastle may indeed be the way to go.
I bought 2 TMART no-logo 2010's (gifted one), and I got friends that bought another 4-5 TMART no-logo versions, all without a problem. They all love the light. They are all using 18650's, I'm using KumaBear 26650 KK's and mod'ed with U3 1C and 4.1A driver. Mine hasn't gotten much stress, so no problem w/batteries, though of course my driver spring is changed somewhat better.
Well, wish I knew... Didn't have a light meter at the time, and though I got one now, still experimenting with lux/kcd measurements. I could try to borrow a stock HD 2010 and compare them now, would be interesting... It's a crazy output light, but wondering if the direct drive old driver at 4+A or even 5A could compare to my regulated 4.1A now. It can't compete with my 3.9A 7G9 - that's a throw beast.
Oh - I put in a brass pill, press fit into the large HD 2010 aluminum pill, and put in 5 5/8" 18 gauge copper discs, soldered together, then thermal epoxied in there!
