Baseball field lighting standards and regulations ensure that players, coaches, and spectators have safe and adequate lighting during games and practices. These standards and regulations cover various aspects of lighting, including intensity, uniformity, placement, glare control, and maintenance. The specific requirements may vary depending on the level of play (e.g. professional, amateur, youth), and may be set by governing bodies such as Major League Baseball or local leagues and organizations.
Adhering to these standards and regulations is essential for player safety, as well as the overall quality of the viewing experience for spectators. Modern baseball field lighting systems are often required to meet energy efficiency standards and may be subject to environmental impact regulations.
Requirements for lighting intensity and uniformity
Minimum lighting levels for different levels of play
There are different minimum lighting levels for baseball fields depending on the level of play. These levels are typically measured in lux, which is a unit of luminous intensity. Here are some general guidelines for minimum lighting levels at different levels of play:
Professional
The minimum lighting level for professional baseball fields is typically set at 1,000 lux. This level is intended to provide adequate lighting for players to see the ball and make plays, as well as for spectators to see the action on the field. Some professional stadiums may have lighting levels that exceed this minimum requirement, depending on the specific needs of the team and the preferences of the stadium.
College
The minimum lighting level for college baseball fields is typically set at 500 to 750 lux. This level is generally sufficient for players to see the ball and make plays, and for spectators to follow the action on the field.
High school
The minimum lighting level for high school baseball fields is typically set at 500 lux.
Youth/amateur
The minimum lighting level for youth and amateur baseball fields is typically set at 300 lux.
Baseball infield vs outfield lighting standards
The lux level is typically higher in the infield (around the bases and home plate) than in the outfield, as the infield requires more precise lighting for players to make plays and see the ball. Here are some general guidelines for minimum lux levels on a baseball field:
| Area | Illuminance |
| Infield | 500-1,000 lux |
| Outfield | 200-500 lux |
These are general guidelines and the actual minimum lux levels may vary depending on the specific governing body or organization. Besides, the minimum lux levels may be higher for night games compared to day games, as the lower light levels at night may require additional lighting to ensure adequate visibility.
Regulations for lighting uniformity across the baseball field
Lighting uniformity is a crucial factor in ensuring the safety and visibility of players on a baseball field. Regulations for lighting uniformity typically specify the maximum allowable difference in lighting levels between different areas of the field, such as the infield and the outfield. This helps to ensure that players have consistent visibility and are not disadvantaged by uneven lighting.
Maximum allowable difference in lighting levels between the infield and the outfield
Regulations for lighting uniformity often specify the maximum allowable difference in lighting levels between the infield and the outfield. This helps to ensure that players have consistent visibility and are not disadvantaged by uneven lighting. A common guideline for this difference is 50%, meaning that the lighting level in the outfield can be up to 50% lower than the lighting level in the infield.
Maximum allowable difference in lighting levels between the home plate area and the rest of the field
Regulations for lighting uniformity may also specify the maximum allowable difference in lighting levels between the home plate area and the rest of the field. This helps to ensure that players have consistent visibility and are not disadvantaged by uneven lighting. A common guideline for this difference is 25%, meaning that the lighting level in the home plate area can be up to 25% higher than the lighting level in the rest of the field.
Placement and positioning of baseball stadium lights
Minimum distances from the field for light poles
The minimum distance from the stadium for light poles is typically specified in regulations to ensure the safety of players and to prevent interference with gameplay. The specific distance requirements may vary depending on the height and type of light poles, as well as the level of play (e.g. professional, amateur, youth).
| Level of competition | Minimum distance from the baseball field and light poles |
| Professional | 50-100 feet |
| College | 40-80 feet |
| High school | 30-60 feet |
| Youth/amateur | 20-50 feet |
Height of light poles and fixtures
The specific height requirements may vary depending on the level of play (e.g. professional, amateur, youth) and the specific needs and preferences of the team or organization.
| Level of competition | Baseball field light pole height guideline |
| Professional | 80-100 feet |
