Abstract
Disclosed are methods and apparatus for lighting control. Reduced intensity light output is provided from one or more light sources (100, 300, 400) based on user proximity. Providing reduced intensity light output from the light sources based on user proximity may facilitate user interaction with a user interface (140, 340, 440) that enables control of the light sources and/or additional light sources. For example, the reduced intensity light output may make viewing of and/or interaction with the user interface more pleasant that non-reduced intensity light output.
