Hi, You will find many opinions as to safe light use/types etc.
First as reccomended find out how safe it is. If you can do the coint test and not notice an issue after 5 to 10 minutes you are ok. (Not all papers react the same).
I leave mine ON when printing, have for decades. I use flourescent tubes with OC filters and bouced the light off a white ceiling.
A word of warning for anyone reading... THE NEW HIGH EFFICENCY SPIRAL BULBS CONTINUE TO FLOURECE AFTER THEY ARE SWITCHED OFF... THEY MAY FOG FILM IF THEY ARE IN YOUR LOADING ROOM!
