Why Switch to LED?
Less Energy
LEDs use 75-85% less electricity than incandescent bulbs for the same brightness. A 10W LED replaces a 60W incandescent.
Longer Life
LED bulbs last 15,000-25,000 hours versus 1,000 hours for incandescent. One LED outlasts 15-25 traditional bulbs.
Lifetime Savings
Each LED saves $100+ over its lifetime in electricity and replacement bulb costs. A typical home saves $200-300/year.

Frequently Asked Questions
What LED wattage equals a 60W incandescent bulb?
A 60W incandescent bulb produces about 800 lumens. An LED bulb producing the same brightness uses only 8-10 watts. This means LEDs use about 85% less energy for the same light output.
How much money can I save by switching to LED bulbs?
Replacing a single 60W incandescent bulb with an LED saves about $8-10 per year (at average electricity rates and 3 hours daily use). A home with 30 bulbs can save $200-300 annually by switching entirely to LED.
How long do LED bulbs last compared to incandescent?
LED bulbs last 15,000-25,000 hours compared to 1,000-2,000 hours for incandescent bulbs. This means one LED can outlast 15-25 incandescent bulbs. At 3 hours daily use, an LED lasts 13-22 years.
Are LED bulbs worth the higher upfront cost?
Yes. While LEDs cost $2-5 each versus $1 for incandescent, the energy savings pay back the difference in 2-4 months. Over the LED's lifetime, you save $100+ per bulb in electricity and replacement costs.
What does lumens mean for LED bulbs?
Lumens measure light output (brightness), while watts measure energy use. A 60W incandescent produces 800 lumens. When buying LEDs, match the lumens to your old bulb: 450 lumens = 40W, 800 lumens = 60W, 1100 lumens = 75W, 1600 lumens = 100W.
Can I use LED bulbs with a dimmer switch?
Yes, but you need LEDs labeled "dimmable." Non-dimmable LEDs may flicker or buzz on dimmer circuits. Some older dimmer switches may need to be replaced with LED-compatible dimmers for smooth operation.
What color temperature should I choose?
Color temperature is measured in Kelvin (K). Warm white (2700-3000K) mimics incandescent and is best for living spaces. Cool white (3500-4100K) works well in kitchens and bathrooms. Daylight (5000-6500K) is ideal for task lighting and offices.
