4 Pieces Photocell Sensor Switch Dusk to Dawn Photocell Sensor Outdoor Photoelectric Switch for Outdoor Wall Porch Light (120V)

Different styles: These photoelectric switch sensors are packaged with NK-GT120VAC 50/60Hz size.
Please check the product size before purchasing.
Easy to use: This photoelectric sensor switch automatically turns on the light at dusk and turns off the light at dawn, without manual operation.
The delay function of the outdoor light sensor prevents accidental triggering of the light due to the headlights of passing vehicles.
Compatible with LED, fluorescent, incandescent and other types of bulbs, so you can use this photoelectric switch sensor for most applications, such as outdoor lighting, outdoor lighting, road lighting, road lighting and doorway lighting.
Easy to install: using the rotary installation method, this outdoor light controller can be easily installed on the precise focusing lamp.
Just disconnect the power supply, put the screw wire of the switch into the faucet hole, and lock it with a rubber washer and zinc alloy nut fixed.
Adjustable design: the angle can be adjusted at will, the photoelectric tube can be rotated to achieve a beautiful light direction, and the light can be easily focused on the position you need.

LED – Red LED indicates that the smoke alarm is operating properly, HushTM, and alarm condition. Green LED indicates the presence of AC power.
Photoelectric Sensor – Advanced photoelectric sensor may detect visible particles (associated with smoldering fires) sooner than ionization alarms. Dust cover protects sensor during construction.
Battery Backup (9V Battery Included) – Provides continuous protection even during power outages. Battery Pull Tab eliminates battery installation time and keeps battery fresh.
Test Button – Tests unit’s electronic circuitry, horn and battery function.
Quick Connect Power Harness – Makes installation fast and easy.
