This Lightbulb Doesn't Need A Dimmer To Set The Mood

    Does it really work? We tested it out.

    Nanoleaf Bloom is a futuristic-looking light bulb that promises to save you energy.

    Does it work? We asked for a sample to see for ourselves.

    It even fit in our tiny reading lamp.

    For those who don't speak lightbulb, here's how three lights you've seen fare.

    A lumen (lm) is a unit of measurement for brightness. A watt (W) is a unit of power, or how much energy you need to get that puppy going. Because new energy-saving bulbs use fewer watts to operate, shopping can get a little confusing, so what you want to look for are lumens.

    Here's how three other common bulbs break down, per the U.S. Department of Energy:

    Regular (incandescent), 60W: 10-18 lm/W

    Compact fluorescents (CFLs): 35-60 lm/W

    LEDs: 27-92 lm/W

    The Nanoleaf Bloom operates using 120 lumens/watt, making it incredibly energy-efficient.

    So how does the bulb save energy?

    What about money? Is it worth it?

    The verdict: Pretty damn cool.

    Want to change your incandescents for energy-efficient bulbs?

    Here's a handy chart and guide from the Federal Trade Commission about what lumens you need and what to look for the next time you shop. The U.S. Department of Energy also has tips for saving money.
