Bright ideas to make your budget go further.

  • Replace outdated lighting with ENERGY STAR® certified lights, which last up to 25 percent longer and use up to 90 percent less electricity than older incandescent bulbs.
  • Make use of natural light sources during daytime hours with blinds and skylights.
  • Turn your lights off during the day, which can save up to 40 percent.
  • Use dimmer switches to save energy and change the mood in a room.

Lighting Facts
Lumens indicate the brightness of a bulb, whereas watts measure energy use.

Watts (Energy Use) Lumens (Brightness)
Incandescent Bulbs CFL Bulbs LED Bulbs Light Output
100 watts 23 watts 20 watts 1600 lumens
75 watts 18 watts 15 watts 1100 lumens
60 watts 12 watts 10 watts 800 lumens
40 watts 9 watts 8 watts 450 lumens

Light color is measured on a temperature scale referred to as Kelvin (K). Lower Kelvin numbers mean the light appears yellower.

  • 2700K – 3000K produces warm white light, the standard color of incandescent bulbs.
  • 3500K – 4100K generates cool white light, which is good for kitchens and work spaces.
  • 5000K – 6500K yields blue-white light, or “daylight,” which is ideal for reading.
