These lights were so perfect for my event. I initially bought one and went back and got another one. Just one will cover a pretty big space and they are super easy to set up. I personally like the blue because it's not as bright as the others and blue is generally a calming color. Awesome product!
I purchased four of these. They are of typical good Blisslight quality. Well packaged and arrived quickly. Sadly, due to the visibility curve of human sight, the blue versions are nowhere near as bright and impactful as the greens. I'm using these in a more non traditional way of accompanying laser shows and, they'll find some uses but any ambient light really diminishes the effect of these.
