The green LEDs are remarkably efficient. Or the emitted wavelength is spot on the maximum spectral response of the human eye. That should be about 530nm, pretty close to 532nm which happens to be the emitted wavelength of a frequency doubled Nd:YAG laser. Compared to the LEDs I used before, these green ones are almost too bright. I had to up the resistor from about 100Ω to 390Ω to get an acceptable color balance. I'd love to see such a boost in brightness in the remaining two colors as well.
