Padel Court Lighting Standards: Lux Levels, EN 12193 Classes and Permit Compliance

The reference document is EN 12193, “Light and lighting — Sports lighting”, adopted nationally without technical change, so you will also meet it as BS, DIN, NF, UNI, NP or PN EN 12193. It is not a product standard: it does not tell you which luminaire to buy, it tells you which class a court belongs to and what that class has to deliver in lux, uniformity and glare.

Two layers sit on top of it: the national or regional rule governing what your installation sends into the sky and into the windows next door, which is where a project is most often refused; and the electrical installation rule, which decides whether the circuit, the earthing and the protection are acceptable.

Practical note. The document that stops a project is rarely the standard. It is the municipal ordinance, which may be stricter than the national rule and is written by someone who has already dealt with complaints about a nearby court. Ask for it before the lighting is designed, not after.

Illuminance is measured horizontally, at court level, in lux. The class sets the average and the uniformity, and the average on its own is meaningless without the uniformity figure next to it.

Two qualifications matter in a purchase order. Published reproductions of the standard's tables differ in the last decimal: some quote a uniformity of 0.5 for the recreational class and 0.6 for club play, others 0.6 and 0.7, because the value depends on whether the court is indoor or outdoor and on how the national body reads the table — the Spanish sports-facility guidance, for example, works with 300 lux and 500 lux at 70% uniformity, which is stricter than the European minimum. Ask for the uniformity figure explicitly and write the agreed number into the specification; a design that meets the average and misses the uniformity is the most common failure in submitted files. And indoor courts are lit a step above the outdoor equivalent, because the roof and walls remove the daylight that softens an outdoor court.

The class is also a commercial decision. A court sold at 200 lux cannot host a federation event, so the honest question is not “what is the best lighting” but “what will this court be booked for in three years”. The gap between Class III and Class II is roughly one extra pair of fixtures — far cheaper now than a retrofit later.

Four figures travel together in a compliant design, and a quotation that gives you one of them has given you none:

Average illuminance (Emed) is the 200, 300 or 500 lux of the class, measured on a grid over the playing surface rather than read from a single meter position in the middle of the court. Uniformity (Emin / Emed, and Emin / Emax in some national tables) is the ratio between the darkest point and the average: a 300 lux average with 120 lux in a corner is not a 300 lux court, because the ball disappears against a dark background on exactly the smash that decides the game.

Glare is normally capped by a glare rating of GR 50 for the club and competition classes outdoors and GR 40 or lower indoors, with a UGR limit quoted instead in some specifications; in padel this is not only comfort, since the ball is followed against the glass and the mesh. Colour sits in the 4000 to 6500 K range with a colour rendering index of 60 or higher for club play, rising to 70 or 80 where the court is televised, and flicker-free drivers become a requirement as soon as the court is filmed or streamed.

All four are properties of the whole installation rather than of the luminaire, which is why pole layout decides them. Mounting heights of roughly 6 to 8 m, asymmetric sport optics and a controlled tilt — typically no more than 20 to 30 degrees — push light onto the court and keep it off the neighbouring plot. Two powerful units aimed down the middle of the court will hit the lux figure in a sales document and fail the uniformity figure in the calculation grid.

Modern LED luminaires run at roughly 140 to 170 lumens per watt, which is what makes the load figures above possible at these lux levels; metal halide installations that were compliant when they were built often are not compliant now, because lamp output falls well before the court is relamped. Keeping the poles and changing only the luminaires is usually the cheapest route to a compliant class, but it is still a fresh photometric calculation, because the optics have changed. The full range of padel court lighting systems, poles and controls we build follows the same class logic.

Light trespass is the light from your installation that lands where it was not intended: on a facade, through a bedroom window, or into the sky. Spain regulates it explicitly in RD 1890/2008, which divides the territory into four zones and caps the vertical illuminance measured at the window. The values below are those an outdoor court is normally designed against, taken from the light-trespass table of the regulation; they apply to the vertical plane at the height where a window can be affected.

Those four numbers explain most of the design compromises on a padel project in a residential area. If the nearest housing is 15 m away and the site is classed E2, the answer is not a brighter court but a better-aimed one: backlight shields on the luminaires facing the houses, poles set on the far side of the court where the layout allows, and a dimming profile that drops the court after the last booked slot. A dimmable installation is the cheapest insurance against a complaint, and in many municipalities the curfew is a permit condition anyway.

Check your own ordinance before design starts. Municipal limits can be stricter than the national zone table, and councils that have already dealt with complaints tend to write very specific conditions: no light above a stated level at a stated address, at a stated hour.

An outdoor padel court is an outdoor lighting installation, and in Spain that means the outdoor lighting instruction of the low-voltage electrical code applies to it: a dedicated circuit with its own protection, correct earthing, and surge protection where the drivers are exposed.

Ingress and impact protection. IP65 is the floor for an outdoor sports luminaire, and IK08 or better matters specifically on padel, because the poles and the luminaire bodies sit inside the playing volume and take ball strikes. A luminaire with the right lux figure and the wrong IK rating is a warranty conversation waiting to happen.

Driver access. Drivers fail first, so they should be replaceable from ground level or from a service position without a platform, and the junction boxes should sit above the drainage or flood level of the court.

Indoor and covered courts. Inside a hall or under a full canopy the rules change shape: emergency lighting becomes part of the design, heat build-up has to be allowed for in the driver specification, and the structure has to accept the luminaires without weakening the roof. Ask for the as-built circuit schedule and the installer's electrical certificate as part of the delivery, not afterwards — both are normally required in the permit file.

The installed luminous flux you need is the illuminance level multiplied by the court area, divided by the utilisation factor of the optics and the maintenance factor that accounts for dirt and LED ageing:

Installed lumens = lux × court area ÷ (utilisation factor × maintenance factor)

Take a 20 × 10 m court (200 m²) sold as club play, so Class II at 300 lux, with a utilisation factor of 0.45 for a sports optic at the mounting height and a maintenance factor of 0.8:

300 × 200 ÷ (0.45 × 0.8) = about 167,000 installed lumens

Run the same formula on any quotation. If it does not clear about 167,000 maintained lumens for a 300 lux court, either the level or the uniformity is going to fail — and the only way to know which is to see the calculation grid.

For a court being prepared for federation tournaments, the class is documented in the homologation file alongside the dimensions, the surface and the enclosures — and lighting is the item most often left to last.

• A lux figure with no photometric study behind it, or a single “average lux” presented as if it settled the question. Ask for the calculation grid; a real design produces one in an afternoon.
• No uniformity and no glare figure, and no mention of which optic is aimed where.
• A high lux promise from two or three floodlights. It is arithmetically possible and geometrically wrong.
• Watts offered as a substitute for lumens, optics and class. The customer is buying illuminance on a court, not kilowatts on a pole.
• The maintenance factor and ageing ignored, so the court is compliant in the study and non-compliant after three years of use.
• No mention of IP or IK rating on a court where the fixtures live inside the playing volume.
• Light trespass not addressed, and no dimming or curfew option offered when housing is close — the difference between a compliant installation and a complaint.
