   So each PCB requires 3 channels?  I noticed that you put 2 PCB's inside an enclosure. So did you use 6 channels for that one fixture or did you jumper it?  How may amps are you pulling per PCB when all LED's are on?  I am looking at power supplys and trying to figure out which one to buy.  Thanks.

	I have 3 channels per light - the reds, greens, blues and + are y'd together. I don't know what amperage they are drawing but it can't be that high. I used a simple cheap old ac adapter to test the boards as I built them and the DCx16 power supply is from an old computer 4mm tape drive unit.

	Ok, well i will go with a 5 or 10 amp 12 volt DC power supply then. Any bigger than that and the dimensions of them become too large. I am planning on running 5 fixtures of two PCB's with each DCx16. So do all of the positives coming from each channel on the DCX16 get tied together and then just run one positive to each PCB? The negitives are used to trigger?

	I checked with Darryl and the DCx16 is positive common.. I actually run them to each light then they are tied tocether inside the light. I used ps/2 cables from computers because it was conviently 6 wire and have the nice small plugs. The got some 20 to 100 foot ps/2 extensions so I can pretty much put them anywhere in the yar if I wanted.
