Programmable occupancy sensors that control the on/off operation of a fluorescent lamp automatically determine loss of lamp life as the lamp is used. The programmable occupancy sensors can provide lamp life status and can automatically alert a user when a lamp is nearing its end of life and should be replaced. The occupancy sensors are also programmable to automatically improve lamp life and energy savings by selecting an optimal time delay from among a number of selectable time delays at which to operate the sensor. The selection is based on an occupancy pattern sensed by the sensor over a given period of time. The optimal time delay, which prevents the lamp from turning off immediately after last sensing occupancy, extends lamp life by limiting the number of lamp off/on transitions, which shortens lamp life, in view of overall energy usage and lamp usage.
