Innovation of the week: Smart lightbulbs to help you sleep better

Bright lights can interfere with the body's natural sleep cycle, which is why a new lightbulb from GE is designed to encourage more shut-eye, said Jacob Kastrenakes at The Verge. The C Sleep, one of two new connected lightbulbs from GE, automatically changes color to match the sun's light throughout the day: "Bright blue to wake you up in the morning, a standard orange tone for midday, and a softer yellow color for the evening."

The idea is that when experiencing the patterns of natural light, "your body will have an easier time waking up, staying awake, and then falling asleep on time." The bulbs can also be dimmed or turned on and off with a smartphone app. A starter bundle with four bulbs — including the C Sleep and C Life, for midday lighting only — is available at GE's website starting at $49.99.
