The HALO RL56 Bluetooth recessed downlight is the perfect way to get started with smart home lighting, whether you're looking to outfit your entire home or just a single room. All you need to set it up is a Bluetooth-enabled device and the free HALO Home app; unlike other systems, there's no internet connection or "hub" required. Once installed, you'll be able to easily control and program the lighting from your mobile device-from color temperature fine-tuning and dimming to set the mood, to automatic scheduling and even voice control (via Amazon Alexa or Google Assistant, when you add the Internet Access Bridge). And with a wide range of HALO Home indoor/outdoor fixtures and accessories to choose from, you can expand and customize your smart lighting to your heart's content.
