I have a number of Kodak Carousel projector which uses 82V 250-300W bulb. I want to convert one of them to a slide copying device. I am looking for the lamp bulb that I can install in the projector as it but has much lower wattage like 50W or so. I need to diffuse the light and the 250W bulb would melt my diffusing plastic. There are many low wattage MR16 bulb but they are 12V or some low voltage and not 82V.
