I'd like to replace my safelights with LEDs.
In theory LEDs should make a perfect safelight source since (excepting so-called white LEDs) they emit on a single wavelength. This also presumes that someone makes an LED that falls into one of the sensitivity "gaps" in the paper spectrum.
Did Kodak or Dupont (or anyone else) ever publish the spectral characteristics of the various safelight filters that were recommended for various photo papers?
I suppose instead of starting with the safelight data you could start with paper spectral sensitivity, but I don't seem to have a good source for that either.
Any ideas?
