An LED lamp power management system and method including an LED lamp having an LED controller; a plurality of LED channelsoperably connected to the LED controller, each of the plurality of LED channelshaving a channel switchin series with at least one shunted LED circuit, the shunted LED circuithaving a shunt switchin parallel with an LED source. The LED controllerreduces power loss in one of the channel switchand the shunt switchwhen LED lamp electronics power loss (P) exceeds an LED lamp electronics power loss limit (P); and each of the channel switchesreceives a channel switch control signalfrom the LED controllerand each of the shunt switchesreceives a shunt switch control signalfrom the LED controller

LED lamp power management system and method

An LED lamp color control system and method including an LED lamp having an LED controller; and a plurality of LED channelsoperably connected to the LED controller, each of the plurality of LED channelshaving a channel switchin series with at least one shunted LED circuit, the shunted LED circuithaving a shunt switchin parallel with an LED source. The LED controllerdetermines whether the LED sourceis in a feedback controllable range, stores measured optical flux for the LED sourcewhen the LED sourceis in the feedback controllable range, and bypasses storing the measured optical flux when the LED sourceis not in the feedback controllable range.
