      How to hook up a potentiometer to the driver

      When hooking up a potentiometer, use the Dim + and Dim - wires on the driver (grey and purple) and solder them to the 1 and 2 or 2 and 3 prongs on the potentiometer. It doesn't matter which prongs (1,2 or 2,3).

      Customer Reviews

      Based on 50 reviews
      Great light!

      Awesome light! However I don’t like that you have to solder on your own potentiometer. If you don't have any welding experience it can be hard to figure out how to do. It is an easy process however once you get it attached and running! Dims from about 100 watts to 620 out of my wall. Definitely started packing on some weight and getting bigger yields when I added this to my setup! Worth your money and having a payment plan/option makes this very convenient

      Impressed with this light

      Easily assembled and appears to be quality components. Been using the light for a couple of weeks now and I like it so far. Great light for the money.

      HLG 600H

      High quality light. Easy to assemble. Definitely, the best bang for your buck! Extremely powerful! A potentiometer and wattage meter makes everything right.

      Doesn’t get any better than this !!

      Great light ! Glad I made the decision and picked this ! Assembling was very easy. And best of all electric bill is much lower. Definitely grabbing another one ASAP ! Even built a mounting bracket for the dimmer switch


      This thing is like the sun. It’s awesome! I was kind of concerned about the assembly. Although the price difference for the amount of light you’re getting I had to try. Was INSANELY easy! There’s a guy who made a YouTube video that I watched and it’s seriously a cake walk!

      Website is awesome and I used the finance option which is also awesome! There’s no reason to have crappy grow lights anymore!
