i don't understand your last post,
Did you mean that if i would use it like this:
how would you recommend to drive this LED with LM317 if i would want to run it of
two 3,7 v battery's connected in series (7,4 V) ?
and on Product Information about this led on that page it says:
- Forward Current If(AV): 1A ---( i thought that if i want to run it on 90 % power that it needed 900 ma )
- Forward Voltage VF Max: 3V
explain to me what does all 3 things mean especially the first one.
