The FL300 Grow LED top-light is a 550 watt fixture emitting light in the photosynthetic active region of the visible light spectrum. These LEDs would suit most modern production greenhouse and grow room environments, and are designed to withstand the harsh environment of a glass house and keep working year after year. The minimalistic design means easy installation using standard connection technology, and with a minimal shadow footprint, the FL300 Grow is able to produce good quality plants year round.

The FL300 Grow is equipped with a patented active cooling system that enables a low LED temperature and therefore a long lifetime that a passive cooled LED fixture does not have. It also boasts a patent-pending optical lens system that enables a traditional installation plan similar to HPS with homogenous distribution profile on plant level – but with less waste of light. The light spectrum can also be designed for individual crops in combination with DGT by Senmatic’s LED Light Controller or LCC4 Climate Control systems.

The FL300 Grow is CE marked according to standards in horticultural lighting and ROHS compliant.
