Current high bay light fixtures, such as those used in warehouses, are energy inefficient because they are slow to warm up and cannot be dimmed. The Barling Bay Clinic team designed, built, and tested a multiple-bulb, energy-efficient light fixture that automatically adjusts to ambient light and alerts the user to when bulbs need to be replaced. These features allow the fixture to provide the same brightness as older light fixtures but with reduced energy use with a more efficient maintenance system.
