Earthmate Dimmable Candle CFLs have the same attractive look as incandescent candle bulbs but they are much more energy efficient. They are made with a candelabra base and come with a medium base adapter, so they can be used in any household socket. With a CRI of 82, they provide high color rendition in any room. Earthmate Dimmable Candles are designed to dim to 5% of their light output with standard dimming circuits so no additional equipment is needed.
