Tune the microclimate

The powerful and compact BU50 covers up to 50 m² of turf with high-quality HPS grow lighting technology. This makes the unit well suited for high-wear areas on the golf course, such as greens, tee surrounds and other intensively used zones. The nine lighting fixtures deliver a high light output while radiating both light and heat, creating optimal growth conditions when natural sunlight and ambient temperatures are insufficient. Easy to operate and reposition, the BU50 is a practical, user-friendly solution and a valuable tool for greenkeepers focused on maintaining consistent turf quality.

Proven technology worldwide

As the world’s first grow lighting system developed for natural grass surfaces, HPS technology has a long and proven track record. By emitting light and heat simultaneously, the BU50 is particularly effective in situations where turf requires both additional light and warmth, especially during cold, low-light periods. On golf courses around the world, greenkeepers rely on the BU50 to support recovery and maintain high-quality playing conditions during challenging climatic conditions.
