The Philips Hue LightStrips are the most flexible light source imaginable; attach it to any solid surface and extend by up to 10 metres when you want to.
With two metres of LightStrip and a power adapter, you'll be able to start making your lighting imagination a reality. Bend, shape or cut the LightStrip to feature under your coffee table, along your worktop or even around your favourite piece of artwork. Simply use the adhesive tape to secure and plug in the power adapter to the mains.
Use the Ambilight+ Hue app on your iOS and Android Smart devices to control your lights from anywhere, set light schedules for easy home automation or even sync to your favourite music.
