Hi
I bought a Cree XML T6 (10W 3.3V 3A) from a Chinese ebay seller.
The problem is, I cannot get more that ~0.85A-1A of current on it.
I tried driving it with a buck-converter (3.2V), 3.3V PSU rail, and directly from a Li-Po battery (3.5A).
According to the CREE specs, 3.3V should be enough to get to 3A, but the max i got was 1.02A when directly hooked onto Li-Po battery.
In my knowledge PSU and Li-Po should act like a constant current source.
Can anyone advice me or confirm my suspicion about the fake CREE.
Kind regards.
