Yes - I got 2 lights, 3 sleeves, 1 AAA carrier/holder.
Stock light had no thermal grease or epoxy under the star - very bad!
Ok - my stock measurements:
SONY 26650: 2.0A tail, lumens: 493 @start, 442 @30 secs (notice the big drop off - no thermal grease)
Of course I had to start modding right away... Actually went pretty quick, for me that is, but I don't consider this a classic "full mod"...
Mods:
- moved LED+ wire to before the resistors
- 22 AWG silicone wire added inside + spring
- 22 AWG silicone for LED wires, shortened to min length
- XM-L2 U2 2C on 20mm Noctigon, sanded on backside, added GC Extreme under the star
- used NO-OX-ID on driver contacts, retainer ring threads, body thread
- Notes: left plastic centering ring as is, stock lens, no tailcap spring jumper
Results:
SONY 26650: 3.0A tail, lumens: 748 @start, 745 @30 secs -- nice tint!!
Notice how the output really held well? Nice direct thermal path MCPCB, nice thermal grease!
If jumping the battery neg. to the body, I measured 833 lumens @start, so, the tail spring has got to be wired!! Big loss's from the spring. I've seen this exact effect soooo many times...
More Mods:
- 22 AWG silicone wire added inside tail - spring
- sanded down top of LED alignment piece from 2.68mm to 2.56mm, took a little off the inside as well
More Results:
tail spring wire - lumens: 816 - 792 (still SONY)
alignment piece - lumens: 830 - 799 (still SONY) -- SONY is done to 4.06v, 2.93A now
Various battery tests:
Powerizer: 3.23A (4.18v), lumens: 915 - 884

LG HE2: 3.35A (4.21v), lumens: 915 - 881
