I dunno, it’s kinda cool. I’m sure it can be turned off. Best if you can set the color, like you can with most LED light strips.
I would like to see the effect of super-duper-intense invisible-spectrum UV LED lights. Surrounding uV-reactive stuff (like cotton) would glow, but, you would not want to stare uncomprehendingly at the light so you didn't go snow-blind.
