grow lights in the world.


Fohse fixtures are built to last. Industry-leading durability ratings give you peace of mind that your fixtures can withstand the hazards of any grow environment. Plus, every fixture is rated to provide ample photons for well over a quarter century of practical daily use. With Fohse, you get the most efficient and the best professional led grow lights in the market.


The efficiency of a lighting grid goes much deeper than its efficacy rating at full power. LEDs operate at peak efficiency at lower power levels. Unlike under-powered fixtures, Fohse fixtures are engineered to be gradually ramped up over the course of your grow cycle. The net effect is the most efficient use of energy the entire duration of your grow cycles. We fabricate the best LED grow lights available today.


We make the most powerful fixtures in every wattage class. Custom lensing drastically reduces wasted light by directing all that power where it matters most. Coupled together, these features eliminate the neverending labor costs of 'chasing canopy' associated with keeping under-powered fixtures 6-inches above your ever-growing canopy.
