Claim:
1. An LED lamp for producing biologically-adjusted light output comprising: a base; a housing attached to the base; a drive circuit configured to electrically couple to a power source; and a plurality of LEDs; wherein the plurality of LEDs includes a mint LED die, the power spectrum of which has a notch or trough in the 460-490 nm region; wherein the mint die exhibits a power spectrum in which the maximum intensity of radiant power in the 470-480 nm range is less than 2.5% of that of the peak intensity of the die; wherein the drive circuit is configured to operate the plurality of LEDs such that a peak blue output intensity level, in a visible spectral output range of between 380 nm and 485 nm, is between 0% and 10% of a relative spectral power of any other peaks in the visible spectral output above 485 nm.
