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- Replace outdated lighting with ENERGY STAR® certified lights, which last up to 25 percent longer and use up to 90 percent less electricity than older incandescent bulbs.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.
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.
