Featuring a high CRI of 95 indicating accurate color and output equivalent of a 450W tungsten fixture, the SmartLED50 Bluetooth LED Bulb from Smith-Victor is a light source with a household screw-in base that can be controlled remotely with your iPhone or tablet using a free app. The bulbs can be individually turned on/off or dimmed, or you can group several bulbs to create 'zones' for different rooms in a house. Each room can be assigned a group number which can be adjusted wirelessly.
