forward: Every 12V/20W halagen transformer can be used to power a 12V/20W
halogen bulb. But... Every halogen bulb is not a projector bulb. Bulbs for
slide projectors have a special construction and you will get a disturbed
picture when you use an ordinary halogen instead. If you're talking about
another projector so *what* projector? Where can we find the site you're
talking about? What do you really want to achive?
