The past few years, I have bought a few of these, and built up a collection of these bowls, they are fantastic for stage use, with having used them for bands, acoustic acts, theatre and q&a style setups, really finishes off a lighting rig, with having that extra eye candy!
The light output on these, same with the RGBA colour mixing, are pretty good for the price point, and so is the build quality, and partnered with the thon case, and care, these have lasted for me, now having 6 of them.
Overall, a great light, which impressed me at the price point, and a really handy fixture to have when designing a lighting rig and flexible to how it can be rigged, thanks to being nice and lightweight.
