This unique electric fragrance lamp in conjunction with our fragrant salt is designed to enhance any room with a refreshing aromatic fragrance. 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 fragrance or light you desire in the area. The fragrance lamp can serve as a nightlight, or create a relaxing mood with soft light and wonderful fragrance. The lamp is safe to use in any area of the home. You get fragrance and light with no flame. Simply place fragrant salt onto the small glass dish on the top of the lamp, plug it in and adjust the dimmer to the desired level of fragrance or light. The warmer uses a 35W halogen bulb. Replacements are available through us or at most hardware stores .
