I also source my LED's from Ebay, the white ones from UBIDITNOW are a
very good price. $33 for 100 10000mcd whites, inclusive of shipping so
that's only 33cents per LED. They are doing 20,000mcd leds for $79
inclusive of shipping too.
I do find them to be a little on the flaky side sometimes though.
I use these LED's for making a small (15 LED) front lamp for use on a
motorbike. I just use a very simple cct to run these in groups of 3
with a single current limiting resistor for each group of 3. I find
that every now and then one LED will blow :(
I guess you pays your money and takes your choice.
