## LED vs Incandescent Energy Savings
LED bulbs use 75-85% less energy than incandescent bulbs while producing the same light output.
### Formula
**Annual kWh = Wattage x Hours/Day x 365 / 1000 x Number of Bulbs**
**Annual Savings = (Old kWh - New kWh) x Electricity Rate**
A 9W LED replaces a 60W incandescent with equivalent brightness (800 lumens). Over 10 bulbs used 5 hours daily, the savings add up quickly.

Ejemplo Resuelto
Replacing 10 incandescent 60W bulbs with 9W LEDs, used 5 hours/day at $0.13/kWh.
- Old annual kWh = 60 x 5 x 365 / 1000 x 10 = 1,095 kWh
- New annual kWh = 9 x 5 x 365 / 1000 x 10 = 164.25 kWh
- Annual savings = (1,095 - 164.25) x $0.13 = $121.10
