I need to run multiple traditional 12v MES bulbs, 2 watts each, and use
old toy train transformers, which can provide an amp or two, which
rather limits the number of bulbs each transformer can power. Usually
around ten bulbs each.

Seen on eBay for 10 - 15 pounds LED Switching Power Supplies, which
output 12v 150w, and therefore capable of powering 75 of my little
bulbs. Would that work? Any reason not to use an LED supply to light
incandescent bulbs?

Thanks
