    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

          Awesome light. Shipping was very fast. I'm reading some of the other reviews and I've had no problems and mine came with all the hardware. I would highly recommend this product for a 4x4 tent and it has a great price point compared to other higher end lights. You can't go wrong with it. Invest your money in a good light one time and you want be disappointed.

          Richard G.

          They are ok but some of them dim than brigten without touching them. One of them they sent me a replacement switch that was different than the one that was in there and didnt send me the wholebox just the reastat so had to take it apart unsolider replace and resolider the part which they sent which wss not the same part that it came with which i had to go get at the hardware store. Also the price was different each time I bougbt them. Has not been a very good expirence. Will deffently look elsewherefor lights in the future. Also when i called the person I talked to made it like they were doing me a favorby talking to me. Overall not a good experiance.

          Love HLG

          I thought the 550's were bright, the 600 is killing the 4x4. Thank you Erik for all the help.

          No hangers in one light box

          I called two days ago about no hangers in light box Rspec 600, and nobody has called me yet. After saying that they would, I bought two lights the other was all right ready to go and works fine. I just wish they would make things right so I can get my room under control.
