This LED light has a lot of features and very smooth colors for such a cheap device. I had no trouble creating pastel hues and beautiful amber tones. The pure colors are strong and even.
The build quality seems very good and overall the par can feels solid and reliable. There is a multitude of functions so the unit is perfectly fine as a standalone or connected to a DMX controller. All of the settings are done via a small LED display which is definitely handy for setting up in poorly lighted conditions. The menu is simple and easy to access, no DIP switches to mess around with here.
The light output is mediocre though. It is great for small(er) black-boxes and stages. But for outdoor venues or larger rooms the 28 watt it brings is more of an ambiance than main light source. But for this price you shouldn't expect the strength of a floodlight or even a 300W Par64 can from a LED unit. So you will definitely need a lot of those if you intend to use them as your main lighting solution for larger rooms.
But for what they are those LED cans preform admirably and I will definitely get more of them.
If you think you might want to use them as floor mounted units, I would strongly recommend getting the STAIRVILLE FOLDING FLOOR STAND BLACK, its cheap, fits this LED can perfectly and the resulting combination is very sturdy and solid.
