💡 Did you know? Replacing just one incandescent bulb with an LED saves about $6–$10 per year in electricity costs.
Most households save 75–85% on lighting energy costs by switching to LED bulbs. For an average home with 20 bulbs used 3 hours per day, annual savings typically range from $150 to $300 depending on local electricity rates and usage patterns.
LED bulbs typically pay for themselves within 3 to 12 months through energy savings. With an average LED bulb costing $3–$8 and saving $10–$20 per year in electricity, the payback period is usually under 6 months for bulbs used several hours daily.
LED bulbs use roughly 15–20% of the wattage of incandescent bulbs for the same light output. A 60W incandescent equals about 9–10W LED, a 100W incandescent equals about 15–16W LED, and a 40W incandescent equals about 5–6W LED.
