Why Choose Energy-Efficient Lighting?
Lighting accounts for about 15% of a household’s electricity use, but by switching to LED light bulbs, you can save an average of $225 per year on your energy bill. Compared to traditional incandescent bulbs, LEDs use up to 90% less energy and last much longer, making them the best choice for homeowners looking to cut costs and energy waste.
If you’re still using incandescent bulbs, upgrading to energy-efficient lighting is one of the fastest ways to reduce energy bills while maintaining the same brightness and quality of light.
Best Energy-Efficient Lighting Options
LED Bulbs (Light Emitting Diodes)
Best for: General home lighting, outdoor lighting, and specialty fixtures
- Most energy-efficient option available (40-80 lumens per watt)
- Lifespan: Up to 25,000 hours (about 15 years with normal use)
- Cost-effective: While LEDs may have a higher upfront cost, they save more money in the long run due to their efficiency and durability
- Features: Available in dimmable, color-changing, and motion-sensing options
CFL Bulbs (Compact Fluorescent Lamps)
Best for: Areas where lights stay on for long periods, such as living rooms and kitchens
- More efficient than incandescent bulbs but less efficient than LEDs
- Lifespan: Around 8,000 hours (3x shorter than LED bulbs)
- Operating cost: Higher than LEDs because they require more wattage for the same brightness
- Contain mercury, requiring proper disposal
Incandescent Bulbs (Traditional Bulbs)
Best for: Limited use cases (not recommended for energy efficiency)
- Least energy-efficient option, with most energy lost as heat
- Lifespan: About 750 hours (much shorter than LEDs and CFLs)
- Running cost: About $169 per 25,000 hours (compared to $30 for LEDs)
For long-term savings, LEDs are the best investment for energy efficiency, followed by CFLs.
Additional Ways to Save Energy with Lighting
Besides choosing energy-efficient light bulbs, you can maximize energy savings by using smart lighting controls:
Dimmers & Timers
- Dimmers allow you to adjust brightness levels, reducing electricity use
- Timers automatically turn lights off when not needed, saving energy
Motion Sensors & Daylight Sensors
- Motion sensors turn lights on only when movement is detected
- Daylight sensors switch lights off when natural light is sufficient
Outdoor Lighting Solutions
- Use LED floodlights and solar-powered LED lights for outdoor spaces
- Choose ENERGY STAR®-rated outdoor fixtures designed to withstand harsh weather
