The fixture is a high performance LED grow light for horticulture cultivation. The compact design with a built-in driver balances the energy efficiency and human work environment. The innovative V-shape design on the LED panel improves light distribution, which lowers the height from canopy needed as it reduces light energy loss. Four spectrum channels including UV, White, Deep Red and Far Red are fully controllable to dial in the exact recipe of light your plants need (only available on TrolMaster HCS-2/3 controller). It provides great external control ability and allows up to 256 fixtures per channel with outstanding efficiency at 2.7 umol/J.
