I purchased this as I was making some glow drinks for the first time and didnt want to waste money on the full tube light. What a mistake, it can barely get a slight glow from Tonic water or a yellow highlighter... I don't see how people are reviewing these things positively like they are the greatest thing... If you want a black light effect, purchase a tube black light. Done
