The difference between illuminating a Standard Squash Court & a Glass court

Illuminating a Standard Squash Court

  • Given the small size of a black Squash ball, the court must use ‘indirect’ lighting, we want to create a whiteboard effect in the background to illuminate the ball as best as possible.
  • Using ‘direct lighting’ will increase glare, this will cause what’s called the halo effect (from light scatter within the eye)
  • The introduction of the LED is somewhat of a problem, an LED chip is a very concentrated light and must be used in the correct setup. Very often we see the fluorescent tubes being exchanged for LED tubes because of the economic benefits. However, this will brighten up the court but cause eye strain and glare discomfort.
  • The introduction of Edge-Lit LED fixtures will solve the problem. Also used on LED tv’s, the indirect light offers visual comfort for the eye. As seen in the image below, the LED light source is directed from the fixture edge with a diffusion plate to further assist. To improve the experience we recommend a white ceiling to eliminate contrast.
  • The Edge-Lit panel can be pendant hung, surface mounted or framed into a drop or hard ceiling. Please remember that the fixture must be sturdy, an impact from a squash ball could easily break the average flat panel fixture.
  • Each 50-watt fixture will save 75% energy over traditional fluorescent fixtures and does not contain UV light or mercury, unlike the traditional fixtures.
  • Be aware of low quality LED flat panels, it is reported that low to intermediate priced fixtures can lose up to 30% of output within a year. Another myth, LED’s don’t flicker, they do! look for California title 24 approved products.
  • The standard lighting requirement (500 lux) requires (9) fixtures for singles and 12 for doubles
  • The optimal setup is (12) fixtures for singles and (16) for doubles. Lux levels (without glare) are now @ 780 lux
  • The light temperature should be 5000 Kelvin (daylight)

Illuminating a Glass Squash court

  • A white squash ball is used on a (colored) Glass squash court, therefore the background should be dark to increase the contrast. (white ball/ dark background) The court is illuminated from very close to the court walls to leave the space above the court with less light.
  • It’s worth mentioning that a white glass court is illuminated like a standard court as a black ball is used.
  • It’s very important to use a single line of light. (see image below) When doing so we eliminate the use of high impact individual light fixtures that will cause glare. (maximum contrast) Instead, the light output is spread around the court evenly and therefore dramatically reducing contrast. The best visual I can give is a white ball traveling over a pedestrian (Zebra) crossing with the eye is constantly having to adjust focus.
  • When using a light source that has a high output we increase the reflectance level on the glass of the court. This makes it extremely difficult to see the ball as it crosses the front wall.
