Rhenac RML 400 mobile turf grow light

Rhenac RML 400 is the largest and most advanced mobile turf lighting system from the German company Rhenac Sports LED, built for professional stadiums and sports grounds. It stimulates growth and fast recovery of natural or hybrid grass and keeps it healthy when sunlight is short — for example, in the shade of the stands or under a closed roof.

The patented CLS® (Complete Light Spectrum®) LED technology reproduces the full spectrum of natural sunlight. Thanks to the multi-channel system, agronomists can set their own “light recipes” for different growth phases: red light stimulates germination, blue strengthens roots and leaf density, and white improves the overall condition of the turf.

Independent infrared (IR) heating modules keep the soil at the best temperature for root development, even in the cold season. Real-time sensors analyse leaf condition and the turf’s response to light; the system can run automatically on light sensors and be controlled remotely from the pitch side.

The design was created together with Turf Lighting Solutions (TLS): the ultra-light aluminium chassis folds without tools, so staff can easily store and move the rig.

According to the manufacturer, 12 years of research with the Technical University of Munich (TUM) show up to 100% more root growth, doubled biomass and 30% longer pitch usage time. Rhenac systems are already used at the Santiago Bernabéu (Real Madrid) and the Veltins-Arena (Schalke).
