Why Switch to LED?
LED (Light Emitting Diode) technology has revolutionized home lighting. LEDs use 75–85% less energy than incandescent bulbs and last 15–25 times longer. The upfront cost is quickly recovered through energy savings.
Direct Comparison: 60W Incandescent vs 8W LED
| Feature | 60W Incandescent | 8W LED |
|---|---|---|
| Power consumption | 60 watts | 8 watts |
| Light output (lumens) | ~800 lm | ~800 lm |
| Lifespan | ~1,000 hours | ~15,000 hours |
| Annual cost (3 hrs/day, $0.25/kWh) | $16.43 | $2.19 |
| Annual savings per bulb | — | $14.24 |
Payback Period
If an LED bulb costs $5 and saves $14.24/year: Payback = $5 / $14.24 = 4.2 months
After that, it is pure savings for the remaining 14+ years of LED life.
Whole-House Savings Estimate
Replacing 20 incandescent bulbs with LED equivalents:
- Annual savings: 20 x $14.24 = $284.80/year
- Over 10 years: $2,848 in electricity savings
- Carbon reduction: ~1 tonne of CO2 per year
Types of LED Bulbs
- A19/A60 (standard): General purpose, replaces traditional bulbs
- GU10 (spotlight): Recessed lighting and track lights
- G4/G9: Small halogen replacement for accent lighting
- Smart LED: Color-changing, app-controlled — higher upfront cost
