Royal Philips, the global leader in lighting, has succeeded in advancing the dimmable LED light bulb beyond just dimming, to become a mood enhancing light bulb that changes color. New Philips LED WarmGlow progresses from a warm yellow white light similar to an incandescent light bulb, to a warmer reddish white light similar to a sunset, as it dims, providing a much richer experience that delivers the right light as required across the home.
