Abstract
A controller for outdoor lighting systems turns lights on and off at predetermined times during the day which are designated by a user. The turn on time is set when the user first turns on the lights. The turn off time is fixed by allowing the user to specify the amount of time that the lights will stay lit. The controller repeats the on-off sequence every 24 hours unless it is reprogrammed. Accurate timing is maintained by counting the pulses in standard 120 V, 60 Hz, line current. A manual override is provided which does not interfere with the programmed time sequence.
