If you still have incandescent or even CFL bulbs in your home, you are paying significantly more for lighting than you need to. LED bulbs have become so inexpensive and so efficient that there is virtually no reason not to switch every bulb in your home today.
LED vs. Incandescent: The Numbers
A traditional 60-watt incandescent bulb produces about 800 lumens of light. An LED bulb producing the same 800 lumens uses only 8 to 10 watts — an 85 percent reduction in energy use for identical light output.
If you run a single bulb for 5 hours per day at the national average electricity rate of $0.16 per kWh, the annual cost is $17.52 for an incandescent and $2.34 for an LED. That is a savings of $15.18 per bulb per year. The average American home has about 30 light sockets. Switching all 30 saves approximately $455 per year.
LED vs. CFL: Still Worth Upgrading
CFLs use about 13 to 15 watts for 800 lumens compared to LEDs at 8 to 10 watts — still a 30 to 40 percent savings by switching to LED. More importantly, CFLs contain mercury, take time to reach full brightness, and perform poorly in cold temperatures. If you still have CFLs, replacing them with LEDs is worthwhile.
The Price Has Dropped Dramatically
In 2012, a single LED bulb cost $10 to $15. In 2026, a multi-pack costs $1 to $2 per bulb. You can replace every bulb in your home for $30 to $60. At $455 per year in savings, the payback period is less than one month. This is one of the single best returns on investment available to any homeowner or renter.
Lifespan Savings
An incandescent bulb lasts about 1,000 hours. A CFL lasts about 8,000 hours. An LED bulb lasts 15,000 to 50,000 hours. If you use a bulb for 5 hours per day, an incandescent needs replacing every 7 months, while an LED lasts 8 to 27 years. Over a 10-year period for 30 bulbs, you would buy approximately 150 incandescent bulbs versus 30 LEDs — saving $100 to $200 on top of energy savings.
Smart LED Bulbs: Worth the Premium?
Smart LED bulbs connect to your WiFi and can be controlled via your phone or voice assistant. They cost $8 to $15 per bulb compared to $1 to $2 for standard LEDs. Dimming your lights by 50 percent reduces energy use by roughly 40 percent. If you regularly forget to turn off lights, scheduling automation eliminates that waste entirely.
Choosing the Right LED Bulb
Color temperature matters for comfort. Choose 2700K (warm white) for living spaces and bedrooms, 3000K to 3500K for kitchens and bathrooms, and 4000K to 5000K for workshops and offices. Look for a CRI of 90 or higher for the most natural-looking light. Make sure the bulb is dimmable if you plan to use it with a dimmer switch.
The Environmental Impact
Lighting accounts for about 15 percent of residential electricity use. Switching to LEDs reduces your lighting-related carbon footprint by 85 percent — eliminating about 500 to 700 pounds of CO2 emissions per year for the average home. Unlike CFLs, LED bulbs contain no mercury.
Take Action Today
Walk through your home and count how many non-LED bulbs you still have. Buy a multi-pack of LEDs at your local hardware store or online. Spend 20 minutes replacing them. Then enjoy lower electricity bills every month for the next decade. This is the closest thing to free money you will ever find in energy efficiency.
