I built one of the LED light sources in the LF thread. The light panel wasn't entirely even so I put a piece of Roscoe diffusion under it. Using a picture frame from Target I spaced it about an inch from the light source and a half inch above the neg carrier. Works perfectly. I haven't had any issues using Ilford VC filters with the panel. An 8x10 neg enlarged to 11x14 has been about 20 sec at f/11 with Arista FB VC paper. Check out the LF thread above, several people have had good success.
