I have a barely used 17" Marineland Hidden blue accent light (460nm). Clean and in box. These work really good. It will give you the ability to have blue actinic lighting only if your lighting doesn't allow that now. Also good if you just need more actinic light. $25. In South Fort Collins.
When you hold it in the air and the lights in the room are dim, how bright does it make the room? I'm considering putting it in my garage where we play beer pong lol.
