With its inner tube and reflective glass coating, the Lightguide bulb give you a glow of brilliantly colorful light, which you can dim to the perfect level. Use any of millions of shades of white or color light to set the mood in any space of your home. Specially made to fit the Lightguide bulb, its fabric-wrapped cord and metal holder (sold separately) — which perfectly covers the base of the bulb — lets you hang your bulb in style. Set the mood instantly with Bluetooth-enabled LED lamps and the Hue Bluetooth app, which allows you to control up to 10 lights in a room. Add a Hue Bridge (sold separately) to your smart lighting system to unlock all smart lighting features.
