Dining Room LED savings: incandescent vs LED
Switching the 6 bulbs in a dining room from 60W incandescent to 9W LED cuts each bulb draw by 85%. Running them 3 hours a day, that saves about 335 kWh and roughly $64/year at the 2026 US-average rate of 19 cents per kWh, or about $640 over 10 years.
Incandescent vs LED for a dining room
| Metric | Incandescent | LED |
|---|---|---|
| Watts per bulb | 60 W | 9 W |
| Total wattage (6 bulbs) | 360 W | 54 W |
| Energy per year | 394 kWh | 59 kWh |
| Cost per year | $75 | $11 |
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 dining room: 6 x 60W x 3h x 365 days is 394 kWh/year with incandescent, versus 59 kWh/year with LED. The 335 kWh difference times $0.16 is the annual saving. At about $24 for 6 quality LED bulbs, they pay for themselves in roughly 5 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 3 hours a day, the LEDs in this dining 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.
