The lamp or luminaire may have: (1) a night/pre-sleep emissions mode in which it emits light having a correlated color temperature (CCT) of about 1,800-2,300 K, the spectral power ratio of blue light (400-495 nm) being such that it constitutes about 10% or less of the total light emitted; (2) a day/wakeup emissions mode in which it emits light having a CCT of about 5,000-8,000 K, the spectral power ratio of blue light being such that it constitutes about 30% or more of the total light emitted; and/or (3) a general lighting mode in which it produces a combined light output having a CCT of about 2,500-5,000 K. The driver may support emissions mode changing based on hysteresis relating to a lighting switch associated with the lamp or luminaire.

A solid-state horticultural lamp is disclosed. The lamp emits a spectrum of light including a first local emission peak between 400-500 nm and a first spectral power distribution (SPD) intensity and a second local emission peak between 500-600 nm and a second SPD intensity, wherein the second SPD intensity normalized to the first SPD intensity is between 0.15-0.35. The spectrum further includes a third local emission peak between 600-700 nm and a third SPD intensity, wherein the third SPD intensity normalized to the first spectral power distribution intensity is between 2.4-2.8. In some cases, a photosynthetic photon flux (PPF) of the light between 600-700 nm is between 3.5-4.5 times a PPF of the light between 400-500 nm, and a PPF of the light between 600-700 nm is between 3.8-4.2 times a PPF of the light between 400-500 nm.

A light emitting element control circuit and power supply for a solid state lamp includes an electrical control circuit controller which enables the operation of a solid state lamp in three distinct modes, which allows the user significant flexibility in operation of the lamp. It enables the user to operate the lamp with a fixed emission spectrum but with intensity control (Mode I); or with discrete settings of blue only or red only or a fixed ratio of the two (Mode II); or an on-demand ratio of blue to red emission whereby the user can operate the lamp with any arbitrary ratio of blue to red for example to meet different spectral requirements of, for example, different phases of plant growth (Mode III).
