First impressions (sorry, due to Christmas I have not time...)
OK, thanks to God, I received the correct ones! (one single mode and one multimode)
Both worked fine with AA after using 14500 (despite today there is a review in DX forums saying that the driver was destroyed with 14500). Maybe long use with 14500 may destroy it... who knows? I have to test, I have no time at all......
I have mixed feelings. With 14500, the 6 mode is brighter than the single mode (with AA is the same output both).
Measured the current draw with 14500:
SINGLE MODE = 1,06A ¿¿??¿?¿?¿ WTF?
MULTIMODE = 1,38A (high) 0,9A (med), 0,2A (low)
I have no instrumental to measure the light output, but "by eye", and comparing to others, I estimate:
HIGH = about 300 lumens (equals a 501B with xpg-R5... more or less)
MED = about 230 lumens (equals F20 on HIGH with 14500... more or less)
LOW = about 10-20 lumens (more or less)
Memory mode = almost inexistent. If you switch on in less than 4-5 minutes, it changes mode. After about 10 minutes it resets to HIGH.
Still much things to test. I have to check what happens to the single mode (maybe the very bad solders it have?)
