Just wanted to add that this light doesn't feel cheap at all. As soon as I lifted it out of the box it was much more solid and heavier than I had expected. It's got powder coated steel. Machined brass hanging mounts. The lenses are PMMA acrylic, and I'd say about as clear as it gets with the human eye. I actually had to ask because I thought it was glass and can't tell you what PMMA acrylic is. The fans aren't cheap quality either, they move some air for 1.6w. The fans pull in from the top, and out the side vents. I'll get a tempgun on it soon in an update. It also has some heft to it, coming in at 7.9 lbs. The 84X also has two drivers. Each has a dual power supply. So, one for each panel.
