3 Ways to Cut Your LED Night Light Energy Bill
- 🌱
Use a model with a built-in light sensor so it only turns on when the room is actually dark.
- 💡
Choose an amber or red-toned LED night light — it uses the same wattage but doesn't disrupt sleep hormones like blue/white light.
- ⚡
Use one strategically placed night light instead of multiple — a single well-positioned light is usually sufficient.
LED night lights are ultra-simple solid-state devices drawing a fraction of a watt with absolutely no surge.
