Calculadora de Ahorro con LED — Fórmula

## How to Calculate LED Savings

LEDs use 75-85% less energy than incandescent bulbs and 30-40% less than CFLs while lasting much longer.

### Formula

**Energy Saved = Bulbs * (Old Watts - LED Watts) * Hours/Day * 365 / 1,000**

**Cost Saved = Energy Saved * Rate per kWh**

### Typical Equivalents

- 60W incandescent = 9W LED
- 100W incandescent = 15W LED
- 150W incandescent = 23W LED

Ejemplo Resuelto

Replace 20 incandescent 60W bulbs with 9W LEDs, used 5 hours/day at $0.15/kWh.

  1. Old annual kWh: 20 * 60 * 5 * 365 / 1,000 = 2,190 kWh
  2. LED annual kWh: 20 * 9 * 5 * 365 / 1,000 = 328.5 kWh
  3. Energy saved: 2,190 - 328.5 = 1,861.5 kWh
  4. Annual savings: 1,861.5 * $0.15 = $279.23
