The HLG300L Rspec Commercial Indoor Horticulture LED grow light is designed to replace a single-ended 600 watt HID. Each HLG-300L uses 2 of our custom designed full-spectrum high efficiency white light quantum boards with Samsung LM301H and Deep Red LED 660nm. This unit is dimmable, with wattage output from 90 to 270 watts.


If you are looking for a fixture to use primarily during the vegetative stage, you want to take a look at the HLG 300L Bspec LED Grow Light. This fixture has a higher range of blue light to really push growth during the vegetative stages.


Note: This fixture comes with a 120 Volt power cord with Nema 5-15P Plug
