Hi Sparky, any 12v DC supply should be OK to power a lamp load, but you may run into problems at start up as the PSU sees a cold lamp as nearly a short cct. Another idea is to use an"electronic transformer" , the type used to power 12 halogen GU10 lamps. Would probably be cheaper too. Bear in mind that these devices dont give DC but a very peaky AC. I once tried to use one into a bridge rec and capacitor. Gave very strange results!. If youve got an old PC power supply you could use the 12v DC output from that. With only a lamp load it would probably not need the fan so would be silent. Would need the PSU start pin on the big white plug shorted to neg to allow the PSU to start. That would be the cheap Scots way!
