Calculate savings from replacing all bulbs with LEDs
Single Bulb Comparison
Formula
kWh Saved = (Old Watts − LED Watts) × Bulbs × Annual Hours / 1000; Energy Savings = kWh × Rate; Replacement Savings = (Annual Hours / Old Lifespan) × Old Bulb Cost × Bulbs; Payback = LED Cost / (Energy + Replacement Savings)
Frequently Asked Questions
How much can I save by switching to LED bulbs?
A typical household with 30 bulbs switching from incandescent to LED saves $150-$300 per year on electricity plus $30-$50 in bulb replacement costs. LEDs use 75-80% less energy and last 25 times longer than incandescent bulbs. The investment pays for itself in 3-6 months.
Are LED bulbs worth the higher upfront cost?
Absolutely. While an LED costs $2-$5 vs $1 for an incandescent, it lasts 25,000 hours vs 1,000 hours and uses 80% less electricity. Over its lifetime, a single LED saves $80-$150 in energy and replacement costs. LED prices have dropped 90% in the last decade.
