Replacing a typical 60W incandescent bulb with a 9W LED saves $60 over 10 years. Scale that to your whole house and you're looking at $400–$1,400 in savings.
LEDs consume 80–90% less electricity than incandescent bulbs while lasting 15–25 times longer. That translates directly into lower electric bills and fewer replacement costs.
If each bulb runs 5 hours per day:
| Type | Annual Cost | Bulb Life | 10-Year Total |
|---|---|---|---|
| Incandescent (60W) | $76 | 1,000 hrs | $890 |
| LED Equivalent (9W) | $12 | 15,000 hrs | $120 |
| You Save | $64/year | $770 |
Plus you only replace LEDs once every 8 years instead of annually.
| Bulb Type | Avg. Price | Lifespan | Wattage | Annual Cost* | 10-Year Cost |
|---|---|---|---|---|---|
| Incandescent (60W) | $1.50 | 1,000 hrs | 60W | $76 | $890 |
| CFL (13W) | $3.00 | 8,000 hrs | 13W | $17 | $184 |
| LED (9W) | $4.50 | 15,000 hrs | 9W | $12 | $120 |
| LED Premium (8W) | $12.00 | 25,000 hrs | 8W | $10 | $108 |

The average home has 40–60 light sockets. Here's how much you can save by switching each room:
Kitchen lights typically run 4–6 hours daily for cooking prep and cleanup.
Main living area often used 6–8 hours daily for TV, reading, or entertaining.
Bedroom lights used 2–4 hours nightly for reading and getting ready.
Even premium LEDs pay for themselves in under 6 months:
In a 20-bulb home, switching everything costs $90–$240 but saves $1,280 over 10 years.

Absolutely. Moving 20 LED bulbs adds only 2 lbs to your box. The instant payback makes them portable upgrades to any home.
Warm white (2700K–3000K) mimics incandescent. Daylight (5000K–6500K) is better for task lighting.
Yes, but check for "dimmable" on the packaging. Non-dimmable LEDs may flicker or hum on dimmed circuits.
Start with the fixtures used every single day: kitchen, living room, exterior lights, and bathroom vanity bars. Then move to bedrooms and task lamps. By replacing the highest-runtime bulbs first, you see the savings quickly and avoid spending money on low-use sockets that barely affect the bill.
This also helps if you care about color temperature. Test warm white in living spaces and brighter daylight tones where you prep food or work.
If you cannot replace every bulb at once, start with the lights that combine long runtime and high wattage. Kitchen cans, exterior floods, vanity bars, and recessed living-room fixtures usually win first. Low-use guest-room bulbs can wait.
This order improves both savings and convenience, because the most annoying bulbs to maintain are usually the ones with the best LED payoff.
LED savings are easy to underestimate because each bulb looks cheap. But the compounding comes from three directions at once: less electricity, fewer replacement trips, and less heat dumped into the room. In summer, every incandescent bulb is also giving your cooling system extra work to do.
That is why lighting upgrades still matter even in homes chasing bigger HVAC or insulation wins. They are one of the simplest permanent reductions you can make.
