Danny Sheldon

Goals of Sports Lightinga solution that will:

1. Create optimum playability for the players to play the game safely and competitively at night

2. Maintain the integrity of the light per IESNA recommendations

3. Provide a system that is safe and pleasing for the players/spectators and is friendly to the neighbors and environment

4. Provide the lowest cost of ownership over an expected 30-40 year life cycle

• Spill Light– The light shining beyond the sports facility caused by

the uncontrolled direct light component from the lighting system.

• Obtrusive Light– Spill light that causes glare, annoyance, discomfort, or

loss of visual ability. Light Pollution.

• Glare– Intense and blinding light. Causes visual discomfort or

disability – Not a function of distance.

Spill light

• Minimize spill, glare and obtrusive light by limiting outdoor lighting that is misdirected, excessive, or unnecessary

• How? Combination of fixture technology and lighting design

The Evolution of Musco’s Spill and Glare Control

Additional Considerations

• Right amount of light, in the right place, at the right time. More light often means wasted light and energy.

• IESNA Guidelines for safety and playability• Photometric Design – proper mounting

heights and setbacks• Automatic on/off controls – consistent

hours of operation
