Ways to cut the cost
- 1
Replace any remaining incandescent/CFL bulbs with LED
LEDs use 75-90% less per socket
- 2
Use ENERGY STAR certified bulbs for longest life
Non-certified LEDs fail early and waste the investment
- 3
Choose dimmable if installed with dimmer — non-dim in dimmed circuits shortens life
