These A19 bulbs have the typical screw base we all grew up with, but use far fewer watts than regular bulbs. The Great Eagle answered my prayers with a 100 watt lightbulb (this model) no bigger than an incandescent bulb! Perfect for ceiling fan lights and works well with my (old) dimmer switch (remember there are LED dimmer switches that work better with LED bulbs). The only problem is that they are poorly packaged for shipping. They come in the relatively thin cardboard box you see in the store with 6 bulbs inside. I would have thought at least a padded envelope would be used, but not in that order. But I am completely satisfied with it and can only recommend it. I have a "warm" color. Please note that "Daylight" models are too intense for indoor use and have an almost bluish tint that bleeds into the eyes. Great Eagle has a wide range of light bulbs with color temperatures. At first I went for daylight, but I couldn't handle it. Replaced with warm instead.
