FluxScale™ Top Light

FluxScale 600AC


FluxScale™ is a connected, fully tune-able broad spectrum horticultural lighting platform designed for greenhouses and high intensity indoor top lighting applications. Featuring our patent pending Precision PAR™ technology, FluxScale™ is the only horticultural lighting solution on the market capable of delivering consistent PAR for up to 10 years. FluxScale™ is also the industry’s first LED fixture capable of delivering both flowering and vegetative PAR spectrums at full power in one fixture, offering unmatched control and efficiency for applications including crop cultivation, seed production, and greenhouse cultivation. 

FluxScale Top Light was discontinued in July 2019; customers with FluxScale lighting will continue to receive software updates, platform upgrades, technical support, and warranty coverage.
