How to Light a Baseball Field

As the sun sets, the excitement of the game continues! That’s why lighting isn’t just about illumination… It’s a fundamental part of every baseball or softball field. Good lighting improves visibility, keeps everyone safe, and ensures the game is fair and fun. The gold standard for sports lighting is established by the Illuminating Engineering Society (IES), whose recommendations help guide the design of safe and high-quality fields.

Most leagues and municipalities use these benchmarks, and adhering to them can also be essential for meeting the requirements of organizations like Little League International, the NCAA, and even MLB.

Let’s start with the basics. Light output is measured in foot-candles (fc), a unit that represents the amount of visible light that falls on a given surface area. And on a baseball or softball field, not all zones are treated equally. The infield demands higher visibility than the outfield, since that’s where the action happens at lightning speed: batting, pitching, base-running, and quick throws. The outfield, while still important, doesn’t require quite as much intensity.

So, what does “good enough” look like? For Little League and youth fields, the IES typically recommends around 50 fc in the infield and 30 fc in the outfield. These levels provide young players with sufficient visibility without overexposing the field or exceeding the budget. Smaller recreational fields can sometimes function at even slightly lower levels, say, 30/20 fc, but that comes with trade-offs in visibility and safety.

Step up to high school competition, and the stakes rise along with the illumination. Most high school fields are expected to meet Class III standards, meaning at least 50 fc on the infield and 30 fc in the outfield. These levels ensure fast-moving plays aren’t missed and that visibility is consistent across the field.

When we move into college-level or minor league play, we’re talking Class II lighting. These fields often push into the 100 fc range in the infield, and 50 to 70 fc in the outfield. The difference is stark: players are faster, the ball moves quicker, and spectators (both in-person and on video) expect better clarity.

At the professional level, think of MLB parks or televised college championships; illumination must reach Class I standards. That means 150 fc in the infield and 100 fc in the outfield. These levels aren’t just about gameplay. They’re designed to support high-speed action and satisfy broadcast requirements for HD and slow-motion replays. Even minor shadows or poor vertical illumination in these settings can degrade the player experience and the viewer’s product.

But lighting isn’t just about brightness. Uniformity is just as important if the outfield looks like a checkerboard of dark and light zones, even a high average foot-candle level won’t save you. Little League guidelines often cap uniformity ratios around 2:1 in the infield and 2.5:1 in the outfield. For professional fields, those numbers drop to below 1.5:1, meaning the brightest spot on the field can’t be more than 50% brighter than the dimmest. That consistency keeps players from losing balls in the air or misjudging plays under uneven lighting.

In short, the higher the level of play, the brighter and more uniform your field needs to be. These aren’t arbitrary numbers; they’re built around safety, fairness, and performance. And if your facility wants to host tournaments, games under lights, or televised events, these are the benchmarks you’ll be expected to hit.

Designing the Right Lighting Layout for Every Field

So you know how much light you need. Now comes the more structural question: how do you deliver it? That’s where pole placement and fixture layout come into play.

At first glance, it might seem like adding brighter lights should do the trick, but without the right pole configuration, even powerful LEDs won’t save you from patchy coverage and frustrating glare.

Let’s start with the simplest configuration: the four-pole layout. This setup is ideal for small softball fields and Little League diamonds, where the outfield fences typically range from 200 to 250 feet. In a four-pole design, you’ll often find two poles behind home plate positioned down the first and third base lines and two more at or near the outfield corners. It’s a cost-effective layout that effectively covers the field’s central play area, particularly for younger players.

But there are limits. The farther a pole is from the area it’s trying to light, the steeper the beam angle needs to be. That creates challenges when trying to evenly cover the deep outfield. For youth fields, that might not be a dealbreaker. But once you step into larger field dimensions, the gaps start to show.

That’s where the six-pole configuration becomes the go-to for high school and many college-level fields. This design still includes two poles behind home plate, but now adds two mid-field poles down each foul line and two outfield poles typically positioned in left-center and right-center. The result is broader, more even coverage with much better uniformity across the outfield.

For most schools or municipalities looking to meet the 50/30 or 70/50 fc standards, six poles strike a smart balance. They offer reliable performance while keeping costs and installation complexity in check.

At the top end, professional venues rely on eight-pole systems. These layouts are highly engineered, often incorporating tall towers that can reach over seating areas and project light deep into the outfield. Here, you’ll typically see two poles behind home, two down each foul line, and two beyond the outfield wall. With lights coming from all directions, you get maximum uniformity and far greater control over glare and spill light.

Using more poles for coverage brings a wonderful advantage… Better aiming precision. When eight carefully positioned poles are used, designers can opt for narrower beam angles and fewer fixtures per pole, which helps lessen glare and cut down on power use without compromising the overall quality of the lighting. This setup leads to fewer shadows, more control, and savings on energy costs in the long run.

Pole height also plays a very important role. Small fields may use poles in the 40–50 foot range, while pro parks might go as high as 120 feet to clear grandstands and maintain consistent beam angles. Taller poles allow more downward aiming, which keeps glare out of players’ eyes and limits light spill into surrounding neighborhoods. Combined with smart optics and AEON’s glare-reducing lensing systems, the result is a clean, professional-grade playing experience.

Of course, adding more poles increases upfront costs both in materials and installation. That’s why it’s critical to tailor your layout to the field’s size, usage, and budget. A four-pole layout may be perfect for a community rec league. A six-pole setup might make sense for a high school chasing district tournament approvals. An eight-pole build could be the difference between an acceptable and an exceptional experience for a college program or minor league club.

No matter which route you go, the key is to plan intentionally. Don’t just copy-paste a lighting plan from another facility. Use photometric analysis to simulate light levels, adjust beam angles, and validate uniformity before any holes are dug. AEON’s design team can help you model the entire system and ensure your lighting delivers where it counts between the baselines and under the fly balls.
