I had these lights installed in my office. Usually I do all my installations but I don't trust myself when it comes to this much electrical so I had a friend help install it and it was a lot easier than I thought it was going to be. Almost like any other light fixture except for a little more support here and there. I have two work spaces in this room which both need extra lighting and this is what this gave me the rotating heads on the track or perfect for aiming the light right where I needed it I couldn't have been happier on one side I do my crafting and the other side is office and it worked out perfectly.
