Energy-Efficient Lighting: Benefits & Guide to LEDs | Energy Upgrade California
Back to Energy Efficiency


An average household dedicates about 5% of its energy budget to lighting. You can save up to $75 each year by replacing your home’s five most frequently used light fixtures or bulbs with models that have earned the ENERGY STAR® rating.

Switching to energy-efficient lighting in your home is one of the easiest ways to save energy and reduce carbon emissions. Imagine lighting your home with the same amount of light, but for less money.

The most energy-efficient light bulbs available today are LEDs, which offer many choices that typically use 75% less energy. Energy-saving incandescent bulbs use about 25% less energy than traditional varieties.

What’s the Difference Between Types of New Light Bulbs?

Incandescent bulbs use a lot of energy to produce light, with 90% of the energy given off as heat. They are also no longer manufactured in the United States.

Energy-efficient light bulbs like light-emitting diodes (LEDs) and halogen incandescent bulbs

  • Provide choices in colors and light levels
  • Will save you money, use less energy and last longer
  • Can be used with outdoor fixtures and will save energy if always on

LEDs are also available as floodlights and can be used in exposed fixtures to withstand weather. Look for ENERGY STAR®–qualified fixtures that are designed for outdoor use and come with features like automatic daylight shutoff and motion sensors.

LED light bulbs

  • ENERGY STAR®–qualified LED bulbs use 20% to 25% of the energy of and last up to 25 times longer than traditional incandescent bulbs
  • LED bulbs use 25% to 30% of the energy and last 8 to 25 times longer than halogen incandescent bulbs
  • LED bulbs are one of today’s most energy-efficient and rapidly developing technologies
  • They work well indoors and outdoors because of their durability and performance in cold environments
