UCB BR18-SH4Q Color Changing Smart Light Bulbs: Works with Alexa only for voice control
These smart bulbs are perfect for anyone who wants to add vibrant lighting to their home without complicated setup. Whether you're setting the mood for a movie night, creating dynamic lighting for a party, or simply adjusting your reading lamp, these bulbs offer flexibility and ease.
While many smart bulbs focus on basic automation, these bring a creative twist. They're not just for turning lights on and off—they're a tool for personal expression. The music sync feature lets your lights dance to your favorite tunes, and the DIY flash modes can make game nights or celebrations more immersive. You'll notice the smooth color transitions when switching from warm white to cool daylight, with no flicker to disrupt your video calls or reading sessions.
Control everything through Alexa voice commands or the BRmesh app. Set schedules to make your home look occupied when you're away, or adjust brightness and colors from your phone. With 16 million colors and no WiFi required, these bulbs provide reliable, colorful lighting that adapts to your daily life.
