Letop Photoelectric Switch
LETOP Photocell switches are used to turn exterior lights on at sunset and off at dawn. Because they sense ambient light levels, photocells automatically adjust to seasonal changes in the day/night cycle and are unaffected by daylight-saving time. Photocells controlling exterior lights combined with timers that turn on interior fixtures create the illusion of occupancy when you’re not home, which can deter intruders.
Other photocell uses include turning on the parking lot or street lights after dark, adjusting indoor dimmers to compensate for changing natural light levels, or switching illuminated business signs on or off. photocells control an entire electrical circuit and are an ideal way to manage security or landscape lighting.
