The most advanced (and priciest) model is the White & Color Ambiance. This version has a white color temperature of 2000K to 6500K. You can adjust the brightness and via the Philips Hue app, you can also choose between a whopping 16 million colors. Whether you want to relax with warm white, boost your concentration with cool white, or create a party vibe with a fancy color -- this is all possible with the White & Color Ambiance bulbs.
