LED lighting is being installed on tennis
- Jul 24, 2019-
A standard tennis court is 78 feet long. In pro matches, a tennis ball routinely reaches speeds in excess of 120 miles per hour. Even an amateur player can achieve ball speeds of between 80 and 100 miles per hour. Within the fraction of a second that is required for a tennis player’s brain to process the motion of a tennis ball, that ball will have moved at least ten feet. Given the tight dimensions of a tennis court and the speeds at which a ball travels, good tennis court lighting is critical for top performance of both pros and amateurs. LED tennis lighting is fast replacing metal halide fixtures as the standard for optimum illumination.
A 300 watt LED high bay fixture will generate the same amount of illumination as a 1000 watt metal halide fixture. Wattage is a measure of how much power a fixture needs to generate a given amount of lighting. Because LED’s are more efficient, they require substantially less power input. That lower power input will allow a facilities manager to save a substantial amount of operating capital solely from lower electrical utility bills. A fixture’s lighting output is measured in lumens. Look for LED tennis lighting fixtures that have a lumen rating that is equivalent to a metal halide fixture’s lumen rating.
By some measures, more than 50% of the light from a metal halide fixture disperses to areas outside of the primary tennis court area. LED fixtures are much more directional and are available with multiple beam spread patterns. Rather than simply selecting an array of the same type of LED fixtures, as a designer might do with metal halide lighting, a designer can mix LED tennis lighting fixtures that have different beam dispersal characteristics to achieve near-perfect uniform lighting across the entire playing surface, with no shadows or dark spots that might affect a tennis player’s performance.
LED tennis lighting is available with CRI’s that are close to or almost the same as natural sunlight, which gives players the best opportunity to see a tennis ball’s trajectory and spin, even at high speeds.
