Each HLG 350R uses 2 of our custom designed full spectrum high efficiency Diablo quantum boards with Samsung LM301H and LM351H Deep Red Diodes. With a rectangular footprint this fixture is ideal for flowering in smaller grow spaces or vegging in a commercial grow.

Features of the HLG 350R LED Grow Light

HLG is known for its Quantum Boards, the world's highest efficiency light engines, and using top-notch LEDs, but these are just a few examples of what makes the HLG 650R one of the best commercial grow lights available. The 660nm red light gives your plants that extra boost during the flowering stage to really round out the effectiveness of this fixture.

Full-spectrum light suitable for all stages of growth

The HLG 350R produces light with a kelvin temperature of around 4000K. This range contains enough blue light to keep your plants happy and healthy during their vegging stage and well as enough orange and red light to take you all the way through the flowering stage. HLG provides an additional range of 660nm deep red to help give a huge boost in the flowering stage to produce bigger yields with higher potency.
