I am really interested in the current draw. (The voltage is fixed, more or less, by the wavelength. So the current will tell us something about the efficiency.) Jens Google "GaAs LED efficiency". According to https://www.ele.uva.es/~pedro/optoele/LEDs/Bright_LEDs.pdf , before 1973 the efficiency was under 1% or under 0.2%, depending on the chemistry. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
