STANDARDS OF LIGHTING
The following recommended standards have been adopted by the Kentucky High School Athletic
Association as a result of recommendations by our Standards Advisory Committee. These recommended
minimum standards were adopted in July, 1999 and apply to the lighting of all high school athletic
activities sponsored by the KHSAA or its member schools.
These standards incorporate the most current data available regarding the lighting, electrical and structural
issues that apply to installation of a safe, effective lighting system. As with any school construction
project, it is recommended that design professionals be consulted early in the planning stages.
The standards are divided into recommended minimums and desirable features. The minimums establish
criteria which are important to safe conduct of KHSAA activities. The desirable features are established to
provide guidelines for lighting systems that give added values of durability, energy-efficiency, environmen-
tal sensitivity as to spill and glare and that are more cost-effective to own and operate.
In most cases, these recommendations will be part of the criteria used to determine championship sites
when the KHSAA makes site selections. These standards comply with the requirements of and are
recommended by the Director of Facilities Management for the Kentucky Department of Education.
I. Recommended Minimum Standards
These minimums are recommended for all lighting installations after the date of adoption of these
standards. Any modification in existing lighting systems after this date should be done so as to result
in a lighting system in compliance with these standards. To be in compliance, a system must meet all
of the recommended minimum standards.
*Natatoriums and field/track venues are currently under study and will be included in the next
printing. In the interim, please call KHSAA office for information.
A.
Lighting
1.
Quantity
a.
Baseball/Softball
There shall be maintained a minimum average quantity of 50 horizontal footcandles on the
infield and a minimum average quantity of 30 horizontal footcandles on the outfield.
b.
Football/Soccer
There shall be maintained a minimum average of 50 horizontal footcandles on the playing
field for facilities for more than 2000 spectators. For facilities with less than 2000 specta-
tors, there shall be maintained a minimum average of 30 horizontal footcandles on the
playing field.
c.
Tennis
There shall be maintained a minimum average of 40 horizontal footcandles on the playing
area.
d.
Gymnasiums
There shall be maintained a minimum average of 60 horizontal footcandles for events with
spectators. For gymnasiums used for recreational purposes there shall be maintained a
minimum average of 30 horizontal footcandles.
e.
Combination/Multi-Purpose
Must meet the highest minimum average among the standards for activities played on field. 5
2.
Quality
a. Baseball/Softball
The quality of the lighting shall be determined on a basis of uniformity and smoothness.
Uniformity of the lighting shall be such that on the infield the highest measure of quantity
of light shall not be greater than 2.0 times the lowest quality of light. For the outfield
measurements, the highest quantity of light shall not be greater than 2.5 times the
measurement of the lowest quantity of light at given target points.
Smoothness
Over the entire area of the infield and outfield, the change in the quantity of horizontal foot
candles should not occur at a rate greater than 10% per 10 feet except for the outside
perimeter reading which may change at a greater rate.
b. Football/Soccer
The quality of the lighting shall be determined on a basis of uniformity and smoothness.
Uniformity of the lighting shall be such that the highest measure of quantity of light shall
not be greater than 2.0 times the lowest quantity of light for fields lit to 50 footcandles or
2.5 times for fields lit to 30 footcandles.
Smoothness
Over the entire area of the field, the change in the quantity of horizontal footcandles should
not occur at a rate greater than 10% per 10 feet.
c. Tennis
The quality of the lighting shall be determined on a basis of uniformity and smoothness.
Uniformity of the lighting shall be such that the highest measure of quantity of light shall
not be greater than 1.7 times the lowest quantity of light within the lines and 2.0 times the
lowest quality of light within the principle playing area.
Smoothness
Over the entire area of the field, the change in the quantity of horizontal footcandles should
not occur at a rate greater than 10% per 10 feet.
d. Gymnasiums
The quality of the lighting shall be determined on a basis of uniformity and smoothness.
Uniformity of the lighting shall be such that the highest measure of quantity of light shall
not be greater than 2.0 times the lowest quantity of light.
Smoothness
Over the entire area of the field, the change in the quantity of horizontal footcandles should
not occur at a rate greater than 10% per 10 feet.
3.
Footcandle Documents
The manufacturer of the lighting equipment shall provide two drawings showing the horizontal
footcandle quantity at each point of measurement on the field. One drawing is to show the initial
quantity of light to be provided when the fixtures and lamps are new. The second drawing is to
show maintained light levels, which should be 80% of the initial light levels. These drawings
shall be in compliance with the minimum standards established above.
4.
Measurement of Light Quantity
a. Area of Measurement
The areas for which measurements are to be taken and the points of measurement within that
area are shown in the appendix. It is important that measurements be taken at all of the
points to meaningfully establish that the quantity and quality standards are being met for the
facility.
b. Method of Measuring Light Quantities
The light sensing surface of the light meter is to be held 36 inches above the playing
surface with the sensing surface horizontal to the ground so that it detects light coming 6
downward to the sensing surface from all directions around the ballfield. Testing equipment
for measurement of light shall be a cosine and color corrected light meter regularly
calibrated in footcandles.
5.
Maintained Alignment
a. Fixture Alignment for Outdoor Fields and Courts
There shall be a manufacturers certification that the light fixture mounting system and the
crossarm to which it is attached are structurally adequate to assure that fixtures will not move
or become misaligned in winds gusting to 125 mph. Because current technology of lighting
equipment has precise intense beams, the misalignment of individual fixtures by a few
degrees can significantly impact on the quantity and quality of light. Also, misaligned
fixtures can result in undesirable glare for players.
b. Pole Alignment
Twisting or leaning of poles can also result in misalignment of fixtures. Foundations for
poles should be designed of sufficient strength to prohibit the pole f
