Lottery is right, or rather a crap shoot…I have the same two brands/makes you have except with exactly the opposite opinion of the two. My generic T-mart one was great (albeit black instead of the grey I ordered) and the Fandyfire was rather disappointing (thicker and bigger opening in reflector, off center led, deep led centering ring led etc). It’s very hard to get a good beam profile on that one.
Can be very annoying when you don’t know what to expect.
Is anyone still selling a good grey original HD2010 with Ultrafire branding?
I was thinking about AMC stacking, but I just got my very first HD2010 in the mail today. It’s a Tangsfire, and it’s giving me a tail reading of 5.3A right out of the box. I don’t think I’ll be switching drivers.
Well, it says the circuit is 1A, and actual lumens are only 388.
Circuitry: 1000mA
Brightness: 900lm (manufacturer rated, actual 388lm)
I don’t know if the actual circuit is 1A and high is direct drive, but 388lumens is pretty low.
I'll definitely take the HD 2010 with more internal space for stacking - was already thinking I'd have to drill it out. Since I can actually get 5A out of a 4.9A Nanjg using a Powerizer, I'll definitely be doing it again (and again...).
Not sure if my post on the last page was missed, can you confirm you have received PP payment. Also add me to the list for the deeper pill for stacking, thanks.
My thinking on the o-ring, yes, I've seen it there and not there... I don't think it's a good thing having it there - the pill thread/contact is for electrical path and thermal path, so, an o-ring serves no purpose being there. It makes the connection feel tighter, but can't see how it may help the metal to metal bonding on the threads. From the pic, looks like vob left space for it and still got 6 threads.
Dunno - I wouldn't go crazy at this point. Your call to weigh the risk/delay/advantage, etc.
Thanks for that, I’ve just returned from the shop and unfortunately the machinist said that he wouldn’t be able to increase the number of threads because it was too close to the top. Sorry about that guys, but I think we’ll have to go with 5 threads for now.
Some changes I made today:
-Ensured that when the HD2010 bezel is tightened down, the stock 16mm PCB has a snug fit and the 20mm copper Noctigon has a solid fit.
-Allocated 25 HD2010 pills for the extended driver space and 15 HD2010 pills for the regular profile (stock 8x AMC7135 and East-92) drivers.
-The PCB contact area will have a nice smooth finish for both pills.
We’re initiated production, will update you guys on further progress.
