I also have a set of four, they are so good, that I tend to leave my 4 saturns, 3 pocket scans and octobeam at home and only employ the 4 accu spots. I've even gotten good at programing using dmx operator II, did a wedding last week, the colors were white and blue, guess what program the accu spot white and blue. For the money nothing comes close to the performance of these lights. Recommendation only let a train person plug in the xlr cable as I let a 15 year old roady do it and he broke the socket, 12 dollar fix but was I mad. He didn't even have the decency to tell me. I had to find out on my own, when they would not sync up. I have used them as spot light on objects, wedding party entrance into the hall, there is no limits to these lights and you. Buy four but you can get by with three, as I did a four of july gig, using red, white and blue. spot and the fourth one had the white stars moving in a circle. while the red white and blue alternate on the other fixtures.
