LED floodlights for sports grounds

The terms are often used interchangeably in everyday speech. The difference lies in the task: LED flood lights for yards or building sites often have up to 200 W and spread widely. A sports ground needs light from 16 m and above, evenly across the whole pitch and with as little glare as possible. That takes the right power, optics and individually aimed floodlights.

• Luminous flux: how much light the floodlight emits, not just the wattage
• Optics: narrow optics such as 20° for long throws, wider ones such as 40° for closer areas
• Light distribution: only LDT data allow the system to be calculated in advance
• Protection rating: IP against water and dust, IK against impact
• Light colour: 3000, 4000 or 5000 K
• Weight: matters for the structural capacity of existing masts
• Controls: dimmable, switchable in scenes and zones

• STL963: 960 W, 146,700 lm at 3000 K, four individually tiltable modules, 20 kg. For smaller facilities and few masts, for example tennis, padel and training pitches
• STL1443: 1440 W, 219,950 lm at 3000 K, six individually tiltable modules, 27.5 kg. For larger fields with few masts, for example football, hockey and athletics
• STL1500: 1500 W, a single light field with symmetrical optics, 28 kg. For demanding requirements from about 500 lx, for example competition, higher leagues and stadiums

All three are rated IP66 and IK10, come with 20° or 40° optics and are available in 3000, 4000 and 5000 K.

The modules of the STL963 and STL1443 are easy to remove and replace. The LED driver sits directly in the floodlight or, where weight matters, at the foot of the mast. Glare shields are available as accessories for Series 12. The warranty is at least 7 years, depending on the project.

That depends on the sport, lighting class, field size and mast height. For football, DIN EN 12193 for example specifies 75 lx for training and 200 lx for class II. A reliable number only comes from a lighting calculation with the data of your facility.
