A customer contacted Access Fixtures needing to update the lighting in their indoor basketball court. At the time of the call the gym was illuminated using eight 400w metal halide high bay luminaires. While the 400w MH luminaires provided enough light, the customer wanted to update to LED in order to improve light quality, have even light levels, to decrease energy and to stop the frequently required maintenance due to burnt out lamps and ballasts. Additionally, they wanted the instant-on capability that is inherent with LED lighting.
An Access Fixtures lighting specialist designed a lighting system matching the existing luminaires one-for-one using eight 158w LED high bays. This kept the light distribution of the original design. It also used the existing wiring minimizing the cost of labor to complete the project.
The LED high bay luminaires reduced energy use by 66% while providing equivalent light levels. Rated LM70 at 100,000 hours, the LED luminaires eliminate replacing metal halide lamps 6 times, so maintenance costs will be significantly reduced. Based on $0.25/kWh, which is the current cost in MA, assuming the gym lights are operating 12 hours per day 5 days per week, over the course of 10 years each LED high bay will save about $2,400 for a total savings of over $19,000.00.
The LED high bays provide the instant-on capability that metal halide lacks, enabling the lights to be turned on and off without having to wait for restrike and warm-up time. This means the lights can remain off until needed, saving even more energy. Also, the quality of the light, measured by color rendering index, is superior to metal halide. The illuminations is much more even too.
