This is the lightbulb that produces changing colors and soothing scents that work in concert to provide calm and relaxation, available exclusively from Hammacher Schlemmer. Producing 180 lumens—the same light as a 25-watt incandescent bulb—this low-energy LED bulb provides up to 16 million color combinations of differing tones and brightness. Its built-in diffuser requires just a few drops of your preferred essential oil per week and releases its aroma silently and evenly. An app on a smartphone allows you to adjust up to eight lightbulbs at a time via Bluetooth, including white light temperature and intensity, color tone, and speed of oil diffusion (plus on/off control). Fits most lamp sockets. 6" L x 21/2" Diam. (8 oz.)
