Chapter 14 of the USTA’s lighting recommendations for tennis facilities

What is a foot candle? A foot candle is a measurement of light intensity and is defined as the illuminance on a one-square foot surface from a uniform source of light.

Understanding Light Temperature Spectrum

Color temperature from our 5000K LEDs resembles noon daylight from the sun, compared to the 3000-4000K (a household light range) metal halides that many courts still utilize.

What is Photometry?

Photometry is the science of measuring visible light as perceived by the human eye.

Tell us what class lighting you want your club to play under and provide us with the height of your current fixtures, and our engineers will create a photometric study of your lighting project.

Expected Photometry of Tennis Courts

Tennis Courts

GEP’s 4-brick LED fixture will generally get your courts to a class III, while our 6-brick LED fixture levels you up to class II

Pickleball Courts

GEP’s 4-brick LED fixture will get your courts to a class III in most cases, as will our 6-brick LED fixture.

Case Study

This club’s phase I upgrade was only six of its existing courts. CAN YOU TELL WHICH COURTS GOT UPGRADED? Do you see a lot of light pollution off the court? Neither do we … The optics in our LEDs are made to light the tennis court, not the area around the court….

GEP’s LEDs give you the clean, even distribution of light across the playing surface without any shadowing or glare. Our LEDs bleed minimal light pollution to areas surrounding the court (3 FC 10’ off the court) and offer instant on/off to make the playing experience that more enjoyable at night.

GEP’s LEDs make your night match feel like a daytime practice session.


You can clearly see the difference between a court with 8-1000W bulbs vs our 8-LEDs. The metal halide foot candle average for their courts was 28 FC (with 8 fixtures per court) which is below the USTAs class III foot candle average of 50 FC.

The upgraded courts foot candle average is 107 FC (using our 6-brick LEDs) and now meets class II competitive play for the USTA of 75!!!

You can also easily see the difference in color temperature from our 5000K LEDs (which resembles noon daylight from the sun) compared to the 3000-4000K (equivalent to household light) metal halide.
