Methods and apparatus for providing circadian-friendly LED light sources are disclosed. A light source is formed to include a first LED emission (e.g., one or more LEDs emitting a first spectrum) and a second LED emission (e.g., one or more LEDs emitting a second spectrum) wherein the first and second LED emissions are combined in a first ratio and in a second ratio such that while changing from the first ratio to the second ratio the relative circadian stimulation is varied while maintaining a color rendering index above 80.

Circadian-friendly LED light sources

A lamp having a front and rear orientation, comprising: (a) a body containing at least one light emitting diode (LED); (b) an electrical connector for operatively providing power to said LED, said electrical connector being rearward of said body and defining a connection plane between said electrical connector and said body, said electrical connector being configured for electrical connection to an electrical interface; and (c) at least one heat sink in thermal communication with at least one of said LED or said driver, said at least one heat sink having a rearward portion extending rearward from said connection plane and enveloping at least a portion of said electrical connector.
