Littte off topic, here's the last HD2010 I did, and I'm thinking, if this was a U2 1A from KD, these #'s could have been better with a real U2 1A or 1C. Wish I had tracked vendor sources of the LED's to the lights I built...
lumens: 1,149 at start, 1,125 at 30 secs, throw: 200 kcd (894 meters) — all on a fresh KK ICR 4000 cell
It just barely made 200 kcd measured at 4.3 meters, so may be 205-210 kcd if measured from a longer distance of 10-15 meters. I think it came out pretty well, really right there where I expected. The light’s body is clean and I like the look in black. Summary of mods:
- UCL/p lens
- XM-L2 U2 1A de-domed on a 20mm Noctigon copper star
- Nanjg 2.8A, added 4 7135’s to bring it up to 4.2A
- 3 copper discs of 18 gauge, 5/8” diameter added for heat sinking to the pill
- brass ring added for mounting the driver, press fit in, dremel’ed the pill to fit
- both + and – springs wired with copper to reduce resistance
- Nyogel on threads, special pricey thermal conductive grease used on pill threads
- Please note the pill is intentionally loose – if it’s full tightened, the emitter sits too far out of the reflector, resulting in much lower #‘s. So if for whatever reason you need to take it apart in the future, count how many turns it takes to tighten the pill down, and re-seat it the same way. Though it’s not tightended down (screwed from the reflector side), the reflectorr sits on it very tightly — must keep the bezel tightened well, and with the expensive grease, both thermal and electrical conection to the pill is strong.
From the owner:
Tom, my flashlight came in on Friday but I didn’t get to play with it until sunday night when I got back home from vacationing with the family and man am I impressed! THIS THING IS INSANE! I think I told you before that I have an LED maglite, and I thought that thing had some power, NO SIR. This HD is FREAKING UNREAL! And talk about how great the flashlight looks just sitting there. Man I am blown away! I honestly didn’t expect this thing to be that powerful.
I played around with the modes and you were right; I really like them. The cycle through is cool with the half click, or if i cycle full clicks fast, but has memory to where if i let it sit for a while, itll stay on the last mode I had it on.
