Hi Rafael,
I found bl-bulbs, like the energy saving bulbs. I have three of them
mounted on a piece of wood. Good thing is, that they don't need any ballast
as tubes. I'v re done A3 size prints. The bulbs are approx. 20 cm from the
paper, and exposure is abt. 20 mins. I started with blended-light bulbs,
100w, but the uv-content is low and cyanos took an hour or so.
