What Rosco filter # for safelight

[Tim Stapp]

I'm setting up my darkroom in the new place after too many years of it being in storage. What Rosco red filter gels are folks using for safelights?

I'm asking because my trusty safe Kodak beehive safelight was ruined in our flood of May 11th of 2022. I have a couple OC safelights, but I want to try some of the OC sensitive FOMA papers, just because.

Going the LED route is definitely a big upgrade as it will give you a lot more light than a regular bulb while remaining safe.

660 μm LED's are safe for pretty much every ortho B&W material.
