3 Ways to Cut Your Outdoor Flood Light (LED) Energy Bill
- 🌱
Use a motion sensor instead of a dusk-to-dawn timer — lights only turn on when needed, saving 60–80% of runtime.
- 💡
Aim the light downward with a shield to prevent light pollution and reduce the brightness setting needed.
- ⚡
Use a photocell sensor to prevent the light from activating during daylight hours, avoiding accidental daytime operation.
LED flood lights use solid-state drivers with no motor, drawing steady wattage with no meaningful startup surge.
