I don't know if this is still going to help you Elton, but may help anybody that at still has this question. Now iff you really really want a safe light, you will have to go to a store that speciallizes or has a darkroom department. But I myself am knew at screen printing, and one thing that I learned from a more experienced person who has done it for a living said that it isn't really neccessary. Just go to a hardware store, or even a drug store, and get a bug light. It is really just a light element that is yellow, and it gives you a comfortable amount of light, and it doesn't emit ultra violet rays. I've only worked it twice but it really did the job.

Yellow flouresent tube bulb. You can buy the ballast for it for 15 euro. The bulbs are 10 euro. Thats what i use in my studio & im not getting any pin holes anymore. Totally solved that problem.
