The HLG 300L V2 Rspec Commercial Indoor Horticulture LED grow light is designed to replace a single-ended 600watt HID. Each HLG 300L V2 uses two custom-designed full-spectrum high-efficiency white light quantum boards with Samsung LM301H white and 660nm Deep Red LEDs.

    This unit is dimmable between 30 and 260 watts

    Don't waste money on similar power grow lights. They will have efficiency in range of 2-2.2umol per watt at best - against the 2.6+ of this beast! Why? Because HLG use Samsung's very best LEDs - not available to others.

    This is a plug a play lamp - not a kit
