This unique electric fragrance lamp is 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 salt a little or a lot, depending on how much scent or light you want in the area. The fragrance lamp can serve as a nightlight, or create a relaxing mood with soft light and sweet smelling scents. This lamp is safe to use in any area of the home. There is no flame. You can adjust the heat level to be safe for any area. Simply place fragrance salt onto the small glass plate on the top of the lamp, plug it in and adjust the dimmer. This oil warmer uses a 35W halogen bulb. Replacements are available through us or at most hardware stores.
