This high-frequency (HF) motion sensor light is a powerful and energy-efficient lighting solution designed for large spaces such as bathrooms, stairways, porches, hallways, warehouses, and parking areas. Operating at just 15 watts, it emits a bright cool white light at 6500K with an impressive luminous efficiency of 110 lumens per watt. The built-in motion sensor features a 40-second auto-off timer that activates when no movement is detected, helping to conserve energy. Functioning as a safety light with a 12W output, it effectively replaces a traditional 120W bulb, delivering up to 85% energy savings. This makes it an ideal choice for high-traffic or large-area applications where efficient and responsive lighting is essential.
