Question 1

How much do LED bulbs save on electricity?

Accepted Answer

LED bulbs use 75% less electricity than incandescent bulbs for the same light output. Replacing 30 incandescent 60W bulbs with equivalent 9W LEDs saves about 765 kWh per year, worth $105 at the national average electricity rate. A full home LED conversion typically saves $100–$250 per year and pays back in weeks to months.

Question 2

How long do LED bulbs last?

Accepted Answer

LED bulbs last 15,000–25,000 hours, compared to 1,000 hours for incandescent and 8,000–10,000 hours for CFL bulbs. At 3 hours of daily use, a quality LED bulb lasts 13–22 years. This means LED bulbs need replacement far less often, adding additional savings beyond energy reduction.

Question 3

Is switching to LED lighting worth it?

Accepted Answer

Yes — LED lighting has one of the fastest payback periods of any home energy upgrade. LED bulbs cost $1–$5 each. Annual energy savings per bulb replacing a 60W incandescent: $6–$15 at typical electricity rates. Payback per bulb: 1–6 months. Many utilities offer LED bulb rebates or free LED programs, making the upfront cost zero in some areas.
