A client named Dr. Jim Gadberry in McQueeny, TX contacted RLLD Commercial Lighting for a very sophisticated indoor sport lighting system.
This was one of our most complex, but ultimately rewarding, systems we have ever designed. It required very precise photometric renderings, along with special equipment made only in the USA.
The facility contained an indoor single tennis court and double racquetball court.
For the tennis court, Dr. Gadberry needed tournament level lighting at a minimum 100 foot candles. For the racquetball court, he needed general sport court lighting.
There were some very special requirements for this project as well.
For starters, the roof had been constructed at a pitched angle. Suspended indirect sport lights would be needed, along with a special junction box that allowed fixtures to hang straight down from the ceiling. We also needed to supply our client extension stems at different lengths to keep all fixtures suspended at the same height.

The racquetball court lighting system required fixtures to be mounted flush with the ceiling. They needed to be made with sturdy impact resistant glass that would withstand direct impacts for high speed balls. The racquetball court lighting system also needed emergency quartz back-up lights in case of power failure. This would allow the system to instantly come on before to the metal halide lights re-strike time and let players to find their way to the door.
Complex sport lighting systems like this obviously need advanced photometric design planning.
We had to develop a 3D model of the building’s interior. Because the system called for indirect lighting, we had to calculate not only luminance, but also the reflectance of walls, ceiling, and the floor.
By doing so, we were successful in rendering a detailed installation diagram for both sport lighting systems. This diagram was passed to our client’s contractor, who was also provided with step-by-step support by designers at RLLD.
By rendering the system in 3D, we ultimately exceeded client expectations.
By factoring reflectance against luminance, we created a tennis court lighting system that exceeded an average of 150 foot candles. The racquetball court was illuminated with near perfect uniformity at 80 foot candles.
After the model was constructed in our software, we knew precisely what type of sport lighting fixtures to provide to our client.
For tennis court lights, we supplied the ISL series indirect court lighting fixtures. These lights run off remote ballasts. They are designed to tru-hang from sloped ceilings, and they house 1000W metal halide lamps.
For the racquetball court light, we provided the SPT Houston series. These fixtures house 320W Pulse-Start Metal Halide Lighting Fixtures. They feature the required high-impact resistant glass, and they feature emergency backup quartz lighting system that compensates for power outages.
