Hi,
These work up to 12V at 3A and only cost $10.
Or
this works up to 18V at 3A and only cost $5.
I've got no experience with either though I have 2 of the second ones on the way as we speak. Bit annoyed I didn't find the LCK ones first though as their mode selection is much better (none of this strobe crap).
Those drivers are for a single Led, what about to use a DC/DC converter? I have the same issue, I am building a light for 6 xml and 6 xpg I am thinking in connect three in serie, four groups.
Some DC/DC converters had adjustable voltage output, but my doubt is about the currents, most of this had a max of 3amps.
Very cheap in ebay...
I have as well a DC/DC that had three adjustments, current, volts and fill. BTW, I dont know hot to adjust the fill funtion...
Would this last be a good option???
