I'll do a more careful test this weekend, but I had the same problem when I first built my darkroom ~4 years ago. I had some hand-me-down old expired Forte paper, and that fogged badly with the LEDs, but the new Ilford paper works perfectly. I like the LED, it makes the room visible, whereas the other safelight is pretty hard for me to use.

It would have been a good idea to test those chemicals. Often surplus film comes with surplus chemicals and it could be usefull it somebody already tested those chemicals. Especially as the data sheets of X-ray film and chemicals use criptical parameters (like develop it in developing machine Kodak type ..., develop so when used with luminescent foil of type a and different for type b). Would be nice to translate those parameters to the ones we use (delta, gamma, shoulder, toe, etc.)
If you read the originators of this thread from day one, they used far different parameters than some of us do now
Such as ISO

Some of us have been using x-ray film since long before it became popular because of price. I discovered it when other orthochromatic films became more and more difficult to find. one box which I am still sing has a use before date of 12/1971. Good stuff.
