These unique electric fragrance oil lamps are designed to fill the area with a refreshing aromatic scent. Unlike candle based oil warmers, you are in control. Use the dimmer to adjust the halogen light to warm the oil a little or a lot, depending on how much scent or light you want in the area. These oil lamps can serve as a nightlight or create a relaxing mood with soft light and sweet scents. These lamps are safe to use in any area of the home because there is no flame. Simply place fragrance oil or a wax tart onto the small glass plate on the top of the lamp, plug it in and adjust the dimmer.
