Understanding Lighting Options

The average U.S. home has about 50 light fixtures - if you change the five most frequently used light bulbs with models that have earned the ENERGY STAR label, you can save $40 each year.

A 60W incandescent bulb will cost $7.50 per year if used 3 hours a day at  $0.11 per kWh.
The same size (60W or 800 lumens) LED will cost $1.50 per year if used 3 hours per day at  $0.11 per kWh.

Using new lighting technologies will use 70-90% less energy than incandescent bulbs


Understanding the Label

Kelvin  = the color a light source produces.

The lower the Kelvin, the warmer (yellow) the color; the higher the Kelvin, the cooler or bluer the color

CRI (Color Rendering Index) = a score from 1-100 that rates a bulbs ability to accurately illuminate color with daylight getting a score of 100.

Lumens = units of brightness



Choose lighting products that contain the Energy Star label.
This is your assurance that this product has met the energy efficiency guidelines established by the EPA and the US Department of Energy.



LED Light Bulb

*LED light bulbs use a fraction of the wattage required to power a bright incandescent bulb.

*No mercury

*Rated to last for decades of use.

*Prices start at $3.50

*LED bulbs don’t burn out. They dim over time; fading to 70% of their original brightness.  If the packaging says it will last 25,000 hours, it will take that long to fade down to 70% brightness.

*Some manufacturers offer bulbs with 10 year warranties.

*An LED costing $5 will pay for itself in energy savings in 2 1/2 years.


How do I get the most from my CFL?

*Screw in your CFL by holding the white plastic part, NOT the glass tubing.

*Don’t turn your lights off too soon.  You’ll maximize the lifetime savings and effectiveness of your bulbs by keeping them on for 15 minutes or more

*Only use bulbs labeled as three-way on three-way sockets.

*Use only bulbs labeled as dimmable on dimmer switches

*CFL’s are sensitive to extreme temperatures.  Most aren’t intended for outdoor use.  If you use them out of doors, look for cold-cathode CFL bulbs rated for temperatures as low as –10F.

*CFL bulbs contain trace amounts of mercury.  Directions for clean up and disposal is available on the package.
