Light Bulb Language
Since January 1, 2012, the Federal Trade Commission has required a new “Lighting Facts” label. It was designed to help consumers break the habit of picking bulbs based on wattage to determine brightness. Now a metric called lumens is used for this task. Wattage only measures the amount of power a light bulb consumes.
Confused? Here’s an example: If you want to replace a 100-watt incandescent with an LED bulb and get the same brightness as the old bulb, you’d need a 27-watt LED bulb with an output of 1,600 lumens.
How to Read the New Label
While the new light bulb lingo sounds pretty complicated, it’s not once you get the gist. Here’s a breakdown of the “Lighting Facts” label:
Brightness: Here’s a quick tip: the brighter the light bulb, the higher the number. Standard bulbs range from 250 to 2,600 lumens.
Estimated Yearly Energy Cost: How does this add up? According to the U.S. Department of Energy, by upgrading 15 traditional incandescents in your home with energy-saving bulbs, you can save about $50 per year on your energy bill. Plus, energy-efficient bulbs produce about 75% less heat, so you may see additional savings when it comes to home cooling.
Life: The life of each bulb is estimated based on the usage described. Keep in mind that labels marked Energy Star meet strict energy efficiency guidelines set by the U.S. Environmental Protection Agency:
Energy Star LEDs use about 25% of the energy and can last about 25 times longer than traditional incandescents.
Energy Star CFLs use about 25% of the energy and last 10 times longer than a comparable traditional incandescent.
