Designed for venues seeking compact, efficient and sustainable pitch management, the RML 400 combines industry-leading LED technology with lightweight rig design, to provide world-class turf growth under artificial conditions. With modern stadiums and training centres under increasing pressure to deliver consistent playing surfaces all year round, often under shade from stands and meeting demanding fixture schedules.

For grounds professionals, maintaining health turf in these conditions requires tools that not only stimulate growth but do so effectively. The RML 400 has been developed to meet these challenges, providing an adaptable, high‑performance solution that integrates seamlessly into the daily routines of venue managers and their teams.

The results are measurable with up to 100% more root growth, double the biomass, 40% fewer input requirements, and 30% more playable hours. With just three RML 400 rigs, pitch managers can achieve full-pitch width coverage with 90% light homogeneity, supporting faster germination and quicker recovery.

Horst Theisen, CEO of Rhenac, explains, “The RML 400, using our LED research from the Technical University of Munich, combines our latest footprint technology and the market’s best homogeneity across 400 square meters, meaning an even coverage with consistent turf quality across all treated zones. For us, it’s not just about one monochromatic light; it’s much more. It’s about creating balanced light recipes that replicate natural sunlight and adjusting temperature to support every stage of turf growth.”

Alongside its advanced lighting technology, the RML 400 benefits from Rhenac’s collaboration with TLS, pioneers of single-row aluminium mobile lighting. This ensures a lightweight, easy-to-handle rig that’s practical for grounds teams to transport, deploy and store. These design benefits translate directly into ease of use for grounds teams. Other features of the RML 400 system include intuitive controls, light sensor automation and smart remote operation from pitch side.

To ensure long-term reliability, Rhenac will provide spare parts for 10 years, and the product will be supported by a comprehensive service model, combining remote assistance with a dedicated international service team. (stadiaworld, 31.10.2025)
