When you want an alternative to a regular scented candle with an open flame to freshen your home, this electric glow bowl unit and gel is a great substitute. This air freshener has a low watt light bulb attached to a base. The cylinder has an indent in the bottom that allows the bulb up into the jar where it is surrounded by the scented gel but is still separated from it by the glass. The glow bowl gel is warmed by the light which releases the scent into the air. Choose any of our gel scents and add about half of the bottle into the glass jar, or you can mix fragrance to create your own blends. The light shinning out through the colored gel crystals gives off a beautiful glow. The unit has a convenient on and off switch on the power cord.
