Sensor-integrated LED fixtures vs. networked fixtures connected to the internet.

In this project, the Lighting Research Center (LRC) of Rensselaer Polytechnic Institute will demonstrate and evaluate LED lighting and controls. The LRC will first evaluate a range of commercially available but currently underutilized control products and systems, from simple stand-alone controls, to fixture-integrated products, and more complex automated control systems. The LRC will review the features, operations, and protocols of each system selected and will analyze the operation of these control products with various types of drivers commonly used in commercially available LED lighting products. Once this review is complete, the LRC will down select two or more control systems to demonstrate and evaluate in different areas of an existing office building. The LRC will also select and install LED lighting fixtures to retrofit the existing fluorescent lighting in the building. Once the systems are installed and commissioned, the LRC will evaluate the operation of the control and LED lighting systems and compare their performance, operation, energy savings, and occupant acceptance to each other, as well as to the previously existing lighting system.
