50 Watt LED
I mentioned recently that I’m planning to attempt to retrofit a Kodak Carousel slide projector into a slide digitizer. I’ve begun to make purchases towards that end. I already have a few projectors. The most complicated parts, which are anything to do with electronics, will be replacing the light source. The 300 watt halogen bulb is very bright and very hot. LEDs generate some heat, as well, but not as much. This is the light source I have picked. It’s 50 watts and should give me a nice, even illumination. I’ll put some pearled glass between it and the slide, to further even things out. I also bought a heat sink with an attached fan and a driver for the light that runs on household current.
