Durst laborator 138 advice

Don't, stop, did you say led array. I'm meant to be plastering the light leaks in my new darkroom. Look at what this guy has done Dead Link Removed. A 5x7 led array, if anyone knows of a guide to building one of these let me know, looks relatively simple (without the electronics) to rig up a simple blue/green array with dimmers. The future seems very bright

I can't comment on his electronics, I don't know a thing about them, but you can get things like this (see link below), pretty easily. Neither can I comment on creating a colour source - maybe if you looked deeper into the same site you'd find something. You only need a couple of sheets of MG filter (00 & 5) to split grade.
But if I was starting from scratch I'd take a good look at LED's they run cool and they give lots of light, perfect for bodging a holder in plywood.
Best of all, doing it this way you're avoiding all the centering and evenness issues with a colour head, just make sure the array is a bit bigger than the biggest neg you intend to print.
