Why didn't I start using them years ago? I just installed a track light above my kitchen counter and decided on these bulbs. I can't get over the fact that I can now control the color and brightness of the lights in the kitchen with my voice! So practical and helpful. When I'm not cooking or cleaning, I like to use them to set the mood. When set to blue they even produce a noticeable black lamp effect, which is fun. I'm tempted to buy a second box to ensure I have the right replacement bulbs for years to come.
