An electronic lighting controller is described which provides a simple and cost effective way to install electronic lighting such as LEDs. The installation is as simple as, or simpler than wiring a traditional mains (1 20V or 240V AC) system and the installer can use the same wiring and switches as used in a standard installation. The installer only has to install wires from the controller to a standard switches and to the electronic lights and does not need to worry out ratings, load types, intermediate switches, etc. The controller consolidates the AC mains input, DC electronic and LED power output and control functions into one unit to reduce complexity and price. The same controller can be used for providing switching, dimming, multi-way switching, multi-way dimming, master off, and master on functionality. Further there is no requirement for complicated control system buses or programming tools such as those found in sophisticated and expensive building automation system.
