I would also like to buy just the pen. Will SFE be offering them?

According to this photon energy-wavelength calculator
if the photon energy is ~3.4 eV (for forward V drop of 3.4 V) then the wavelength would be 365 nm. This is an approximation since I don’t know if the forward voltage drop will give the actual eV of the photon. Does anyone on this know for sure? This is a good UV wavelength, about the same as one of the Hg lines (365 nm) used in early photolitho.
No public wish lists :(
