Eh? At least my samples of SingFire are as good as original CQGs. Possibly even coming from the same factory?
And some answers to questions posted above (and in PMs):
1. Does it really support 10440?
Yes, this light works well both with AAA (Alkaline, NiMH, Lithium, ~1.5V) and 10440 (Li-Ion, 3.7V)
2. Crappy Chinese Emitter?
No. Definitely CREE XP-E, cool white in my samples. Tint is very clear cool white, not green at all.
3. Lumens?
10440: ~140lm initial, ~110lm OTF after 30s (heats up quite fast -> heat sag)
Alkaline AAA: ~40lm OTF after 30s (not much heat sag, pretty much the same with NiMH & Lithium)
4. Current draw?
TC currents in my tests were:
10440: ~1.2A
AAA: 0.5-0.6A
5. Measurements?
11.9mm × 88.3mm
6. Access to pill? No separate head section?
Opens only at tail cap, no idea (yet) how to take off the pill. Same as in original CQG.
Opens at the bezel, pill can be taken away from there. See a separate post for details / photos.
7. GITD bezel O-ring?
Clear O-ring. Not GITD.
8. Clip can be removed without scratching the light?
At least I can remove it without major scratches. Small scratches might occur.
9. How easily would these accidentally click on etc in a pocket with the protruding switch?
Not easily. The switch is positioned so that it's impossible to turn the light on by pressing the tail to floor, but it clicks on easily a short distance after the body boundary.
10. Beamshot?
Still too bright here for real beamshots, see this photo taken at about 2am:
..so this comparison to NW CQG v1 will do:
Did I catch all the questions? Any more questions? :)
