Replace traditional bulbs with these C by GE Tunable White Smart LED Bulbs. These general purpose bulbs provide the perfect white light for every room by adjusting the white tone from warm to cool. Synced with your sleep/wake cycle, these bulbs go from a warm calm light at night to a crisp, to vibrant light in the morning. Now you can set scenes and schedules, group your lights together and dim and brighten your bulbs. Set up is simple—these bulbs will not require a hub or bridge when paired with a Google Home device.
