Most electronic controls such as electronic timers, photo sensors, motion sensors, touch lamps, and remote light controls are designed to work with the simple technology of an incandescent rather than the complex circuitry of a CFL or LED bulb. Electronic controls draw a small amount of electricity to operate that would concurrently run a small amount of electricity through the CFL ballast or LED driver, placing stress on the electronics.
It is possible for electronic controls to be designed to work with fluorescent or LED technology, so check with the manufacturers of the bulb and electronic control device for compatibility.
Note that CFLs can be used with mechanical timers (those that do not use electricity to operate) without adversely affecting the performance. Always check the packaging for an individual product's use and compatibility with controls. ENERGY STAR requires full disclosure of limitations with controls and compatibility information on the packaging or a web site.
