I bought two of these lights and it got to the point were I wanted my money back. The customer service sucks big time. No one ever answers the phone, and these lights shipped directly from china. They state that they will ship the same day that payment is received, but that did not happen. I e-mailed several times asking for shipping info and tracking info with no answer. I felt uneasy having just spent 2400 dollars on these lights. I felt scammed until 8 days later I finally received the shipping info. The shipping was free and they arrived in 5 days. They weight about 35 pounds but they look like they are made pretty well. I have one set up but have not used it yet. I really hope these lights are great and I will be watching this thread to get some tips. Sorry to hi-jack your thread.
