  Just  uploaded  3 photos in Files section so that anyone interrested
  can  see  the  exposure  un  it that I use. It consists 2 Philips TL
  20W/09N tubes with the reflectorc made from 110mm PVC tube cutted in
  half  and  with reflective foil sticked inside. The distance between
  tubes  is  110mm  and the height from glas covered PCB/Film combo is
  approx 200mm. Exposure time 5 minutes. Glas used is ordinary 6mm.
