I was not happy with their service. I did not get the model, k4000-2 that I order from them, or the one in the picture, they send the one from Amazon.

this is by far the best light up to date my plants love love it . the 1000-watt aglix is superer to lights iv tried in the past. I'm still only using it at 75 percent power and my plants are thriving. I'm seeing super fast growth tighter inter nodded spacing. DEFFENTLY A lot closer to sun light then any iv tried in the past. making my crop 40% bigger over all than past grows. I'm seeing remarkable over all better growth better smells ,taste,quality, and quantity just look
