The transformer is just a 10:1 step-down transformer, going from your 
household 120AV to 12VAC. It *will* generate some interference, but 
almost entirely just a 60hz hum. I don't find that wall-warts generate 
too much noise, as there's a TON of wal-wart happening. I think it might 
be interesting to run the halogen straight off of the 15 volts on your 
power supply... OVERCLOCK THE BULB, MAN! (That would, of course, not 
ACTUALLY be advisable)
