With no need for candles, this plug in lamp will warm wax melts or fragrance oils from the heat of the bulb, by touch control only you can control the intensity of the light and ultimately the warming of the fragrance. When switched off the glass is a silvery colour with a pearlescent sheen, and when switched on, it illuminates with a hypnotic and funky circle design. These lamps can be used by adding couple of drops of essential oils or fragrance oils, or easier still by using wax melts. This lamp is predominantly an oil burner, and is not designed to be left on long term as a lamp because it does generate heat. It is recommended to only leave switched on for three hours at a time. Simply touch the lamp anywhere to turn on, off, and brightness.16.5cm high x 10cm diameterSupplied with 35 Watt G9 bulb (don\'t use low energy equivalents, as it needs heat to warm the fragrance oils)Mains operated
