The large Hue Play Gradient Light Tube in black brings a cinematic atmosphere to your home. Place or mount it under a television to create a mix of colorful light. Rotate the light tube in any direction to perfect your surround lighting. Thanks to a built-in LED, this lamp is extremely energy-efficient in operation. LEDs (light-emitting diodes) have the advantage over traditional light sources of not generating heat, instead converting most of the energy into light and thus consuming only a fraction of the electricity.
