Spice up your downlights Okay, those recessed can lights in your ceiling might not be something you think too much about. But what if you could easily change their color and brightness? This White and Color Ambiance Downlight from Hue makes doing just that easy and fun. With this retrofit bulb, you can choose from over 16 million colors and 50,000 shades of cool to warm white light. And you can control it in almost any way you want. No Bridge required One of the only complaints I've heard about Philips Hue bulbs is that you have to have a separate Bridge to control them. Well - not anymore . This new bulb connects to your mobile device using Bluetooth. You can then use the Hue mobile app to control up to ten lights in one room of your home. Use your voice You can also control this bulb hands-free if you've got an Amazon Alexa or Google Home device. That means you can turn your light on or off, dim it, and recall your favorite presets just by asking. Add wall control Operating your lights with an app or your voice is fun, but you might find that some members of the household prefer a good old fashioned wall switch. If so, you can pick up a Hue dimmer to add a wall-controlled option to your Bluetooth-based system. Expand your system with a Bridge to do more If you want to do even more, you can add a Philips Hue Bridge (sold separately). Then, you can control up to 50 Hue devices - even when you're not at home. The Bridge also adds compatibility with other Hue accessories - like the Tap - and voice control via Apple HomeKit and Microsoft Cortana. What's in the Box: 1.
