MGM Evaluates Its Lamp Options for New Office Space

摘要

FOR 755 TROFFERS IN A NEW IT OFFICE SPACE, MGM RESORTS EVALUATED THREE LAMP OPTIONS: 1. A code-mandated minimum of 2×4 linear, 30,000-hour fluorescent T8 lamps (96 watts) 2. Extended-life, 75,000-hour, 2×4 linear fluorescent T8 lamps (84 watts) 3. 2×2 LED, 50,000-hour lamp fixtures (44 watts) Both fluorescent options assumed three lamps per fixture, while the LED option had one module. Each lamp option was evaluated with and without controls. The additional installation cost for controls with each lamp option was roughly $47. The analysis assumed that occupancy controls would decrease consumption for the two fluorescent lamp options by 30%. For the LED option, a roughly 42% usage decrease for controls was projected due to dimming and daylight dimming capabilities as well as occupancy sensors.
