The 550 lighting fixtures in the lobby of the Krannert Center for the Performing Arts were replaced with energy efficient LED fixtures in 2010. The new fixtures are projected to use 132,000 kilowatt-hours and cost $12,500 annually. This cost is about a fifth of the old system’s cost. The newer fixtures also lower cooling and maintenance costs. Another aspect of the installation is a computerized mixing feature that allows Krannert staff to change of the lighting color of each bulb to create a unique atmosphere in the building. The default setting is a warm white light, but red, blue, and green LEDs give the potential for any color to be created.
