Meh, ordered a 200mw 532nm module on ebay, no documentation. Had it running on a constant current psu, by following/guessing the tracks on the pcb and yeah, seemed to work, current seemed high I thought, 5v/300ma but checked the very limited documentation and it said 9-12v anyway. So I tried that, and I must have been using the wrong input, as its now its dead. I'm guessing I killed it. Very dim red glow, and I did think IR, but wont do anything 'fun'. So low efficiency LED it seems.
Got me wondering anyway... why are there so many wires on these little things? I've never really looked at them before.
