RE: Darkening a Darkroom

For alt processes there is really no need to darken the room into a darkroom. I routinely work with a 40W bulb in a bathroom, no windows though. I will turn the lghts off after coating, but I keep the door semi open so I can see at any time and allow air circulation.. The 40W bulb generates so little UV light. Remember that all you alt processes are UV sensitve and not much daylight sensitive.
