LED Lighting Upgrade Savings Calculator
Calculate LED savings from current bulb type, count, and usage hours.
Returns annual savings, payback period, and 10-year ROI from switching to LED.
Annual Savings
LED vs. Incandescent Energy Savings
Annual Savings = (Old Wattage - LED Wattage) x Hours/Day x 365 x Bulbs x Rate / 1,000
Wattage comparison (equivalent brightness ~800 lumens):
- Incandescent: 60W
- Halogen: 43W
- CFL (compact fluorescent): 14W
- LED: 9W
LED advantages:
- Last 15,000–25,000 hours vs. 1,000 hours for incandescent
- 75% less energy than incandescent
- Lower heat output — reduces cooling load in summer
- No warm-up time, no mercury (unlike CFLs)
