Light-emitting diode based products

A lighting system comprising:

• two or more LEDs configured to produce at least two different spectra of radiation;
• a processor including a memory;
• a controller configured to control power delivered to at least one of the two or more LEDs, the controller being responsive to at least one signal communicated to the controller from the processor;
• a light-transmissive material, wherein the two or more LEDs are arranged such that at least some of the radiation passes through the light-transmissive material;
• and
• a user interface coupled to the processor, wherein:
• the user interface supplies a user interface signal to the processor, the user interface signal including at least one of a logic high signal and a logic low signal;
• and
• the processor selects a program from the memory upon receipt of the user interface signal, wherein the processor further comprises a timer configured to measure a duration of the user interface signal, and wherein the processor adjusts a parameter of the program upon receipt of a predetermined duration of the user interface signal.

A lighting method, comprising acts of:

• A) producing at least two different spectra of radiation from two or more LEDs;
• B) controlling power delivered to at least one of the two or more LEDs in response to at least one signal communicated from a processor;
• C) passing at least some of the radiation through a light-transmissive material to provide variable color radiation;
• D) selecting a program from a memory of the processor upon receipt of a user interface signal that includes at least one of a logic high signal and a logic low signal;
• and
• E) executing the program to generate the at least one signal communicated by the processor so as to control at least a color of the variable color radiation.
