Q: Is a photocell floodlight better than a PIR motion sensor one?
A: Both are good; it depends on your application. If you need lighting that stays ON throughout the night, → Photocell is better. If you want lighting that only activates when people or cars pass by → PIR is better.
Photocell-led flood lights are widely used where continuous nighttime lighting is needed, such as parking lots, building exteriors, and street lighting. While PIR motion sensor floodlights are used in corridors, security areas, and pathways where occasional lighting is needed.
Q: How do dust-to-dawn lights work?
A: Dusk-to-dawn lights work by using a photocell (also called a photoresistor or light sensor) that detects the ambient light level and automatically triggers the light to turn on at night and off during the day.
The photocell changes its electrical resistance based on the amount of light it receives: in bright daylight, its resistance is high, which stops current from flowing to the lamp and keeps the light off; when the sun sets and the ambient light dims, the resistance drops, allowing current to pass through and switching the light on. This process reverses at dawn when light levels rise again.
