These are nice replacement bulbs for the standard 40 watt E12 candelabra bulb, that only draws 4 watts each. Our chandelier takes 6 of these bulbs. Using the new LED bulbs, the total current draw of the light is 24 watts, versus 240 watts with the original bulbs, saving us a considerable amount of electricity. They work with our chandelier as well as our sconces. They are dimmable, which is nice too.
