Get alerted to activity outside with this Heat Zenith motion activated security light. It senses movement up to 100' away and within a 240-degree range. Adjust the timer as needed to keep the bulbs activated for a few seconds or for a longer interval. With a photocell that detects daylight and DualBrite technology, there are multiple light levels during dusk and night, reducing energy use. Rugged construction allows this halogen security light to withstand the elements. It uses a pair of PAR 38, 120W bulbs (available separately).
