Styro has done testing as have others, but some diodes shift wavelength better than others, these blue phosphor pumpers seem to gain efficiency and power handling ability with chilling from the tests I have seen, the blues don't seem to shift color easily like the reds do with chilling.I just watch an experiment on youtube with led and liquid nitrogen,
when they submerge a 450nm led to liquid nitrogen, the wavelength is shifted to longer value and looks like it's gone to 490nm
My question is, what if we keep this diode running below 25 Celcius, would it make the efficiency better AND wavelength shift happens, or will nothing happen?
Just curious, because AFAIK no one here running the diode in subzero temp.
