Philips Hue lightbulbs are a cool way to customize your lighting system depending on your mood: They can be automated using your smartphone.
Today, Best Buy is offering $20 off deal, plus free shipping, on the Philips Hue Go Multicolor smart LED system.
You can control this lighting system via your smartphone and the Philips Hue app. The system can be dimmed to match your mood or set to help you wake up with light. You can even link sets of lights through the Philips Hue Bridge (not included in this deal).
