The HLG 600 Rspec® Commercial Indoor Horticulture LED grow light is designed to replace 1000watt HID while only drawing 600 watts at the wall and exuding the light output of 1,522 umol/s!

Each HLG 600 Rspec lamp uses 4 custom-designed high-efficiency white light quantum boards with a total of:

  • 1088 Top-Bin Samsung LM301H white LED arrays
  • 64 Top-Bin 660nm Deep Red LED arrays

This unit is dimmable, with wattage output from 60 to 600 watts. Expect higher intensity and more even coverage in a grow tent, reflective area or a cross over with multiple lamps.

How does this light differ from the HLG 550 Rspec? The HLG 600 Rspec features a slightly larger heat sink and a 600W driver to give you 18% more output for more coverage and bigger yields, compared to the HLG 550 Rspec.

Recommended for:

Grow tents

Grow rooms

Large indoor grows

Vegetative growth and/or flowering

Full-cycle growing from seedling to flower
