After more research on LEDs, I decided to go with goldenzrule's recommendation. It is possible with MRFA-600M to utilize dimmable-rated 120V line voltage LED strips - up to 600W of draw of course. 120V LED strips are becoming quite affordable: I snagged a deal for $4.80/meter, SMD5630, 120 l/m, cuttable every 1 meter. RGB+W is not really technically available for 120V line voltage yet (as an easier install) as they are cruising on 12-24v low voltage band wagon - so I decided to use single color LED's @120V. Just plug it in, how easy is that?

Thanks for everyone's help!
