Only one, an Omega E6 XL (5x7) diffusion cold light which has been used for graded b/w papers. Recently finished a DIY LED light source and replaced the diffuser (had yellowed with age). I've completed the illumination uniformity tests (with and w/o) each of my four lenses and measured their corner falloffs at various apertures. Also completed step tablet tests for response to each Ilford under-lens filters with MGIV paper/developer. Included a 47B tri-color gel filter test; Ilford #5 filter does as well, but without the longer exposure. Everything is GO now. 8x10 negs will continue to be contact printed.
