Frequently Asked Questions
How much do LED bulbs save compared to incandescent?
LED bulbs use approximately 75-85% less energy than equivalent incandescent bulbs. A 60W incandescent can be replaced by a 9W LED, saving about 51W per bulb. For a home with 30 bulbs used 5 hours a day, this adds up to over $200 per year.
How long do LED bulbs last?
LED bulbs typically last 15,000-25,000 hours, compared to 1,000 hours for incandescent and 8,000-10,000 hours for CFLs. At 5 hours per day, an LED bulb can last 8-14 years, further increasing your long-term savings.
Are LED bulbs worth the higher upfront cost?
Yes. While LEDs cost $2-5 per bulb compared to $1 for incandescent, the energy savings pay for the difference within a few months. Over the bulb's lifetime, each LED saves $50-100 in electricity costs.
