We bought four of these, which we use as tighter LED spots on a band stage, to pick out individual areas from an overall LED wash from LED par cans.
They come with a removable fresnel style lens that narrows the beam angle and creates a relatively tight spot that adds more interest than just washing everywhere.
Without the lens they make a wide wash light, but are best used in this way as uplighters or close up to equipment as the wide angle is at the expense of an amount of light output.
We use them on sound to light mode as uplighters around the walls at discos sometimes and they are really nice as they fade between colours on the beat (about a 1/4 second fade) rather than the ususal LED can snap so look much more high end.
They have a kettle lead input, power and DMX loop through and the screen on the back goes out after a couple of minutes so you don't have to stick black tape over all the red LCD screens in your rig either.
