Energy 101 Video: Lumens

March 14, 2012

On March 8, DOE launched 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 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.
