      Key Features

      • Industry Most Power Veg Light for Full 4x4 Coverage
      • Industry Best Reliability of Q90 = 62,000 hrs
      • Industry Best Surge Immunity – Dual Surge (LED + Driver)
      • Industry Lowest Weight Frame



      What is the benefit of using more blue in veg for cannabis?

      A blue-rich spectrum enables a robust morphology of the plant structure prior to going into flower. This helps support plant weight to enable larger buds.

      Will this work for leafy greens?

      Yes this fixture has an ideal spectrum for leafy greens. Although depending on the distance you may need to adjust the intensity.

      What diodes are you using?

      We use custom diodes from the following Tier 1 manufacturers: Samsung, Osram, Seoul, and Cree. They are more powerful than the standard 3030 diodes used in the market.

      What driver are you using?

      We use Sosen and Upowertek drivers which have shown to have the best surge protection on the market.

      What’s the benefit of dual surge immunity?

      Dual surge immunity is an industry first and offers peace of mind. Most reliability issues are due to electrical surges that originate from either the mains or within your electrical network. Having 10kV surge protection on the driver and surge protection on the LED diodes ensures maximum protection from these events. We want our fixtures to be set and forget it.

      Do you ship outside of the USA and Canada?

      We are working on getting local inventory globally. We can ship product from our Los Angeles warehouse globally. Please inquire and we can send you a quote.

      Does it include a dimmer?

      We do have promotional sales that include a dimmer. A manual dimmer is not integrated into the fixture as our reliability studies have shown them as another point of failure. Most commercial grows will be using a 0-10V controller and not a manual dimmer.

      Does Spectrum King offer controllers?

      Stay tuned.
