Energy 101: Lumens
Today, the Energy Department is launching the next phase of the Bright Tomorrow Lighting Prize (L Prize), a competition that pushes for accelerated innovation and drives industry to create more energy-saving lighting options.
And with more high-performance, high-efficiency lighting options set to appear on store shelves — it’s time to change the way we shop for light.
Think about it: For decades, we have been buying light bulbs based on watts — or rather, how much energy they consume.
But with new lighting options designed to use significantly less energy, buying bulbs based on watts is no longer a reliable way to gauge the right level of brightness. That instead takes lumens, which measure how much light you get from a bulb. More lumens means it’s a brighter light; fewer lumens means it’s a dimmer light.
Look for the Lighting Facts Label on light bulb packages to help you find the right lighting option. This new label makes it easy to compare bulb brightness, color, life, and even estimated operating cost for the year.
So when it comes to finding the right energy-saving lighting product, compare lumens to be sure you’re getting the amount of light (or level of brightness) you want.
