Our decorative wickless candle warmers use a safe 25 watt light bulb to melt highly fragrant wax cubes. Each warmer is approximately 6.5 inches tall by 5 inches wide (exact dimensions may vary slightly). Warmers use a standard 120 volt wall outlet as their power source. On/off switch built onto the power cord for safety and convenience. The wax melting tray is removable, making it easy to change fragrances and aids in simple clean up.
