3 Ways to Cut Your LED Light Bulb (10W) Energy Bill
- 🌱
Use motion sensors or timers in low-traffic areas like closets and hallways to avoid leaving lights on unnecessarily.
- 💡
Choose the right color temperature — warm white (2700K) in living spaces reduces the impulse to install brighter bulbs.
- ⚡
Dust light fixtures regularly — dirty covers can reduce light output by 20%, prompting you to add more lamps.
LED bulbs draw tiny, steady wattage through their solid-state driver with no motor or surge.
