The Horticulture Lighting Group HLG 600 RSpec LED light will replace a 1000W HID while only drawing 600 watts at the wall and exuding the light output of 1,529 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 LH351 660nm Deep Red LED arrays

How does this light differ from the HLG 550 Rspec? The HLG 600 Rspec features a slightly larger heatsink and a 600W driver to give you 18% more output for more coverage and bigger yields, compared to the HLG 550 Rspec. All the performance gain for the same $849 retail price.

ETL/CSA certified for commercial grows
