Responding to: ???'s previous message
Mercury tungsten blended lamp - HWL (MBTF) 160W 225V

It fits in stadard light-bulb socket, no need for additional circuitry, acts as 'point-source' so it can't effectively expose more than 20x20 cm board without corner dimming, but from 20cm height - desk lamp, 5 mm plain glass cover, graphic film, around 3 min exposure time (manual positive 70 photo coating) europe size board (150x100 mm) - excellent results for kitchen table photolitography :)

I agree, tubes should be better, but I haven't made exposure unit yet and this works for me so far :)

Hm, 110/220V could be a problem though...

Best luck,
CN
