The IntelliWhite (iW) series from Philips Color Kinetics offers a full range of professional tunable white light LED lighting fixtures. IntelliWhite lighting fixtures combine channels of cool, neutral, and warm white LEDs to offer a range of color temperatures that you can adjust with a simple wall-mounted device. 
By adjusting the color temperature of iW lighting fixtures, from warm (more yellow / red) to cool (more blue), you can instantly alter the emotional effect of a space, and dramatically affect the appearance of objects on display in stores, galleries, and museums. By selecting the appropriate color temperature of your light sources for your environment, you can create the atmosphere you desire, positively influence buyer behavior, and increase productivity in the workplace
