Is it OK for photographic paper?
Asked by: Anonymous
Yes it is. In fact, I have a very tiny darkroom with safelights that are closer to my enlarger/easel setup than they should be and I still have not had problems with light fogging.

Are these still coming broken ( not working ) ? I'm considering purchasing one but I saw the reviews that say it came broken . At that price is it still a good safelight ?
Asked by: Maira
I've ordered these bulbs three times. None have ever been broken. This was the best deal I found. They are used in darkrooms.

is this the same as a Deep Red light? I am working with Harman direct positive paper and an ortho deep red light is what is called for.
Asked by: stephen
It is very red and very dim but if it were me I would contact Harman since they require a very specific red(I think it is a 906?) for their direct positive paper. It sounds like an interesting project.

What distance should it be from the working surface ?
Asked by: Maira
I replaced a ceiling light bulb with two of these bulbs in my bathroom darkroom, and performed a safelight test, which it passes flawlessly. They do not each put out very much light but with two in the ceiling it is sufficient for my 5ftx10ft space. I would assume that it would be safe at any distance if you chose to put it into a desk lamp for example, but I have not performed a test at that distance.

Is it okay to use while loading/unloading color negative or black and white film?

No. It is ment to be used during printing. Film loads must be in absolute darkness.
