Can I use the ImagePro in an ETC Source Four with the 750w lamp?
You should NOT use the ImagePro with the 750w lamp. The additional heat and IR energy generated by the 750w lamp (which is reflected back by the Z-glass in the ImagePro) can damage the reflector in the Source Four. Ironically, the life of the iPro Slide is not significantly reduced by this higher wattage lamp.
