a recent thread "forced" me to dig for one of the few incans I keep useable ... my A2.
Took it out of box and pulled the trigger --> the leds worked, the strion kit bulb not.
Put other batteries in; dis- and reassembled, ..., but only when I took the bulb out of the holder and connected the pins to the circuit, it lit up.
Now reassembled again, the main bulb did work, but it was dim and even more "warm white" than the warm white led from calipsoii's led ring.
Also there was a faint of hissing to be heared from the head ...
Just out of curiosity, I let the A2 run and within a few mins the main bulb was on full power again.
Now, when turning off, waiting, turning on, the main bulb starts low and within 1/2 sec goes on full.
is that the ramping up?
Did the main power of the ramping did not work at the beginning?
It has rested about 1/2 (at least) in the box, but I never noticed that low-then-high before
(I know it has a spike protection, but that it is this visible is new to me)
Any ideas, or own findings with Your A2s?
