Aromatherapy Lamps. These Aromatherapy Lamps have a glass dish that needs to be filled with water and then add a few drops of Oil and turn on the light, the heat of the bulb will cause the scent to diffuse. Caution, Do not put all oil in dish because the scent will be overwhelming. Light Intensity can be adjusted by simply touching metal base and can be left on like a night light. This can be a wonderful way to create a relaxing soothing atmosphere as well as one for romance.
