Thanks pentaxuser, I buy from the european ebays. I can have a safe light for free, I have to go were I got the paper, the old and unused photo lab of my department course. There are still several amber bulbs and two amber safe lights housings.
Funny thing, I loaded int o the holder and processed two sheets of harman direct positive paper with my "not safe light" and it did not get foged. Or it did, but I can not notice in the photo.
Thank you all!
