Essential Info

Incandescent lamps provide light, but they don't provide the same healthy, natural light of the sun. The licensed and patented Evolution 20-Watt CF Full-Spectrum Bulb simulates the full-spectrum natural outdoor sunlight to provide a healthier indoor environment while also saving energy. The full-spectrum bulb also lasts about 10 times longer than standard incandescent bulbs.

What's Included

  • Bulb
  • More Info


    The Evolution 20-Watt CF Full-Spectrum Bulb is a medium screw-base lamp designed to replace incandescent lights in table lamps, recessed down lights, porcelain keyless fixtures, and anywhere else you need energy saving possibilities of a fluorescent lamp.

    Natural light from the sun and sky has a balanced spectrum, rendering colors perfectly. Most artificial bulbs emit light rays in a narrow scope of the visual spectrum. This full-spectrum bulb helps people see better, feel better and creates a healthy indoor environment.

    The 20-Watt CF Full-Spectrum Bulb equals the light output of a standard 75-watt incandescent lamp. Full-spectrum bulbs are also available in 11-watt, 14-watt, and 25-watt sizes (the equivalent of 40-, 60-, and 100-watt incandescent lamps, respectively).

    THOMAS -- shenandoah, PA   3/1/2013
    Bulbs worked as advertised.
    KRISTY -- league city, TX   8/6/2011
    Bulbs arrived on time and unbroken. So far so good.
    NICOLE -- st. louis, MO   2/8/2009
    Perfect! some other reviews said the light was too blue... I don't think so at all. It is more blue than most would be used to because it is natural light and regular incandesent bulbs have a yellow heu. Also not to bright I was worried that it would be too bright for what I wanted which is to provide natural day light for my bird that is having problems with her feathers so I bought the 14w bulb as well but this one is perfect.
    JAMAL -- detroit, MI   1/5/2009
    works as expected
    MICHAEL D -- los angeles, CA   4/16/2008
    Very nice natural light. Shipped quickly and carefully.
    JAMES L -- suwanee, GA   4/5/2008
    Good bulbs, Bright, crisp light
    DAVID -- bemidji, MN   10/7/2007
    Much too blue, reminded me of a badly lit office building or janitors closet.
    JOHN -- boulder, CO   9/16/2007
    Absolutely the best CF lightbulb out there.
    JOHN -- hazel green, AL   6/29/2007
    Pretty disappointed with this one. When I paint, I use full spectrum bulbs so I can get true daylight color. The color from this bulb is very blue, and not suitable for color at all. I expect that the full spectrum intent was for plants only.
    CALVIN -- pasadena, CA   3/26/2007
    We ordered these for the classroom of our homeschooling grand children. Felt like they'd be more alert in light that was closer to sun light. Their experience has been good. We are using two of the bulbs in our office and are delighted...seems less tiring to eyes. With the first shipment one of the bulbs was broken, but as soon as my husband called, your customer service immediately sent out a replacement! Thank you.
    CRAIG S -- fairport, NY   2/22/2007
    So far, works great!
    DANIEL NELS -- arlington, VA   2/17/2007
    Very nice
    LAURA LEE -- spokane, WA   10/18/2006
    fast shipping nice color light
    ELIZABETH -- raleigh, NC   7/28/2006
    excellent lightbulbs. I'm in the process of switching all of the lights in my house to energy effecient bulbs. Thanks for making it so easy to do so.
    BRIAN -- hockessin, DE   6/25/2006
    I love this light bulb. It is a big transition at first, because the light feels a lot colder, and honestly more unnatural than standard bulbs. But after I got used to it, I don't think I can go back. It makes a huge difference in reducing eye strain as well.
    ADAM -- philadelphia, PA   6/15/2006
    The lightbulb works great and gives off lots of light. I enjoy the color of the light much more than the orange light you get from incandescents.
    MARLON -- san francisco, CA   1/11/2006
    Can't find anything brighter and whiter from any other sources besides Smarthome.com
