Hi there,
"Did you read that page?"
Yes, I did. Did you? They are 25 feet long, how many coils in a concentric is that? Blue and green for split printing, perfectly even illumination, no heat, no vibration= really hard to live with. No heat means you can use a double ground glass diffuser panel for zero light loss instead of a heat absorbing glass and mixing chamber with 2 opal or acrylic diffusers which cut the light to 1/4.
"Those things (stripwise electroluminescent panels, I think) cost $75 and run off a 9V battery -- which means they can't output as much light as a pocket flashlight."
Not being funny, but welcome to the 21th century. Have you even seen an L.E.D. flashlight? Bright enough to hurt. It also runs from an A.C. converter. Low voltage = no safety problems. Packard shutter = no timing circuits. I was actually thinking of using the same for a 5X7 enlarger. Just think, you could actually take it on the road if you wanted to, just use a reducer from 12 volt.
