Dynamic light for your TV Mounted on the back of your TV, the Gradient turns your walls into an extension of your screen. The Philips Hue Play Gradient Lightstrip gives you color-changing ambient light that can mimic and extend what's on your TV screen. The possibilities and the Gradient's capability to react are endless. The glare of explosions reaches beyond the confines of your TV. Your home theater takes on the same ambience as the dimly lit cafe on the screen. Game on Gamers can immerse themselves in the strange glow of virtual worlds, the brightness of the stadium, the hot western sun - wherever the game takes you. The light strip can also be set to react to music. Sync it with other Hue color-changing lights in a group and you can throw a legitimate dance party. Dual app control This light strip requires a Philips Hue Bridge and can be controlled with the Philips Hue app. But if you want the Gradient to react to your content, you'll also need the Philips Hue Play HDMI Sync Box and the Philips Hue Sync app. You'll create a new "entertainment area" in the Hue app and control light automation parameters with the Sync app. Made for TV The light strip mounts to the back of your TV with the included brackets. Stick the adhesive-backed clips onto your TV - it helps to lay it flat on the floor for installation - then fit the light strip into the channels following the included instructions. The Gradient will cover three out of four sides behind your screen - top, left, and right. What's in the Box: 1. 119.5" Lightstrip for 75" TV with 6" pigtail (4-pin connector) 2.
