How much money can I save by switching to LED bulbs?

Switching from a 60W incandescent to a 10W LED saves 50 watts per bulb. If used 5 hours/day at $0.14/kWh, each bulb saves about $12.78 per year. With 10 bulbs, that's over $127 annually, plus LEDs last 15-25 times longer.

What is the payback period for LED bulbs?

LED bulbs typically pay for themselves in 2-6 months depending on usage and electricity rates. The payback period = LED bulb cost / annual savings per bulb. With higher usage or rates, payback is faster.

Frequently Asked Questions

Common questions about LED savings and bulb comparisons.

Switching from a 60W incandescent to a 10W LED saves 50W per bulb. At 5 hrs/day and $0.14/kWh, each bulb saves ~$12.78/year. With 10 bulbs, that's over $127 annually. LEDs also last 15-25 times longer, adding to the savings.

LED bulbs typically pay for themselves in 2-6 months. Payback period = LED bulb cost / annual savings per bulb. At $5 per bulb and $12.78 annual savings, payback is about 4.7 months. Higher usage or electricity rates mean even faster payback.

A 60W incandescent produces ~800 lumens and is replaced by a 9-10W LED bulb. For 75W (1100 lm), use 13W LED. For 100W (1600 lm), use 15W LED. Our calculator automatically determines the equivalent LED wattage based on your current bulb type and wattage.
