Living Room LED savings: incandescent vs LED
Switching the 8 bulbs in a living room from 75W incandescent to 11W LED cuts each bulb draw by 85%. Running them 6 hours a day, that saves about 1,121 kWh and roughly $213/year at the 2026 US-average rate of 19 cents per kWh, or about $2,130 over 10 years.
Incandescent vs LED for a living room
| Metric | Incandescent | LED |
|---|---|---|
| Watts per bulb | 75 W | 11 W |
| Total wattage (8 bulbs) | 600 W | 88 W |
| Energy per year | 1,314 kWh | 193 kWh |
| Cost per year | $250 | $37 |
How the savings are calculated
Energy use is bulbs x watts x hours per day x days per year, divided by 1000 for kWh. For this living room: 8 x 75W x 6h x 365 days is 1,314 kWh/year with incandescent, versus 193 kWh/year with LED. The 1,121 kWh difference times $0.16 is the annual saving. At about $32 for 8 quality LED bulbs, they pay for themselves in roughly 2 months.
Bulb life and replacement savings
A typical LED lasts about 25,000 hours versus roughly 1,000 hours for an incandescent, so one LED outlasts around 25 old bulbs. At 6 hours a day, the LEDs in this living room should last well over a decade before replacement, on top of the energy savings above. LEDs also run cool, which slightly reduces summer cooling load.
