Tune the microclimate

The powerful and compact BU50 covers 50 m2 of grass with high-quality HPS grow lighting technology, making the unit ideal for treating high-wear areas of the playing surface, such as the goal mouths. The 9 lighting fixtures provide a high light level and radiate both light and heat to create the optimal growth conditions to promote grass growth when natural sunlight and heat are not sufficient. The BU50 is easy to operate and move across the playing surface, making it a user-friendly grow lighting unit and a valuable asset to the grounds team.

Used by professional sports clubs worldwide

As the world’s first grow lighting system for sports playing surfaces, HPS technology has proven its quality. Because light and heat are simultaneously radiated by the fixture, the BU50 is best suited for those specific situations where the grass requires both extra light and warmth; when it’s cold and dark. With the BU50, the grounds team has extra assistance in carrying out restoration work on the grass. Stadiums worldwide, across various sports, benefit from proven HPS technology, using the BU50 to maintain a high-quality grass playing surface week in and week out.
