What Are the Recommended Lighting Levels for Gyms? | IES 101

General gym exercise needs about 30 maintained footcandles, recreational sports about 50, and high-level competition courts up to 125.

A school gym lit to 50 footcandles can look dim next to a college arena running 125, and both are correct — the target moves with who plays there. The recommended lighting levels for gyms come from the Illuminating Engineering Society, which publishes a separate maintained average for elementary PE, high school basketball, college play, and pro-level competition. Miss the classification by one tier and you either overspend on fixtures or leave players tracking a ball they can’t see.

What Footcandle Level Does Each Gym Activity Need?

Each gym activity carries its own maintained average, from 30 footcandles for elementary PE to 100-plus for Division I play. Every figure below is a maintained average at the playing plane, not the output printed on a fixture box. IES-derived tables disagree slightly at the top two tiers, which is why those rows show ranges.

Recommended Lighting Levels For Gyms: Where The Numbers Come From

The figures trace to ANSI/IES RP-6-22, Recommended Practice: Lighting Sports and Recreational Areas, which covers non-professional sports facilities and includes an annex of illuminance recommendations. IES keeps an Illuminance Selector that displays criteria in US customary footcandles at feet or metric lux at meters. One footcandle equals about 10.76 lux, so 30 fc lands near 323 lux, 50 fc near 538 lux, 80 fc near 861 lux, and 125 fc near 1,345 lux.

Design to the maintained number. Lumen depreciation, dust on lenses, mounting height, spacing, and floor reflectance all eat into what fixtures deliver on day one. IES recommendations are guidance, not law. Adopted building, electrical, energy, fire, and safety codes govern where they apply, and

Uniformity, Glare, And The Checks Before You Buy

A floor can average 50 footcandles while the lane under the basket sits at 20 and the wall behind the backboard glares at 120 — unevenness no average reveals. Uniformity does more for a fast-moving game than the average does: hot spots and shadow pockets wreck depth perception and turn a loose ball into a collision. Vertical illumination — light on faces, wall targets, and the ball itself — decides whether a camera can follow play, and no floor reading captures it.

Glare is the other half of the job. High-bay luminaires bouncing off polished floors, bleachers, mirrors, and glossy equipment throw light straight back into eyes; shielding and beam control fix that, and raw output makes it worse. Where looks, instruction, or video matter, commercial guidance often calls for CRI 80 or higher and one consistent color temperature — a design convention rather than a formal IES standard.

Comparing fixtures gets easier once the footcandle target is fixed, and our tested picks for gym lighting lay out output, glare control, and mounting options side by side.

Work through these before you sign a fixture order:

1. Classify the room: general exercise, fitness floor, studio, school gym, recreational court, or competition venue.
2. Pull the target from the current RP-6 edition or the IES Illuminance Selector, and confirm the exact classification.
3. Lock the unit system — footcandles for US design, lux for metric — and stop mixing them.
4. Choose luminaires on photometric files, mounting height, beam distribution, glare control, impact rating, and controls compatibility.
5. Model average, minimum, uniformity, and vertical illumination with a maintenance factor included.
6. Commission with a calibrated meter at the playing plane, record average, minimum, maximum, and uniformity, then recheck after a relamp or a layout change.
