Energy Efficient Lighting Guide to Save Money in 2025
Last Updated: Apr 22, 2025
What Is Energy Efficient Lighting and Why Does It Matter?
Energy efficient lighting uses less electricity to produce the same brightness as traditional bulbs helping you cut costs and carbon emissions.
Old incandescent bulbs convert up to 90% of their energy into heat. Modern alternatives like LEDs and CFLs are designed to use less power while delivering better performance.
- Lower energy bills - save up to 50% or more on lighting costs.
- Longer bulb life - fewer replacements and less waste.
- Environmental impact - reduce your carbon footprint.
- Better light quality - with more color options and control.
Types of Energy Efficient Light Bulbs (And Which One to Choose)
LED Bulbs: Most efficient and long lasting. Use up to 80% less energy and last over 15,000 hours.
CFL Bulbs: Cheaper than LEDs, but contain mercury and don't last as long.
Halogen Incandescents: Slightly more efficient than traditional bulbs, but still inferior to LEDs and CFLs.
Best pick in 2025: LEDs offer superior efficiency, durability, and control.
LEDs are the most efficient and widely recommended lighting option today, while incandescent bulbs are outdated and wasteful by comparison. If you want a detailed comparison, check out our full guide on LED vs Incandescent.

How to Read Lighting Labels and ENERGY STAR Ratings
- Lumens: Measures brightness
- Watts: Measures energy consumption
- Kelvins (K): Color temperature (2700K = warm, 5000K = daylight)
- CRI: Color rendering index - aim for 80+
- ENERGY STAR: Look for certified efficient products
Avoid buzzwords check for certifications.
Cost Savings and Return on Investment (ROI)
Replacing 20 bulbs can save you over $200 per year.
Businesses can recover investments in 1-3 years.
Check your utility provider for rebates and tax incentives.
