Review: Great fun for our birthday party - These worked really well for our blacklight dance party. We had a fairly large room and these units were enough to fluoresce the whole space. The lights have a warning attached that they get hot, and they do get quite warm, so be careful where you set them. I've only used them for the one party, but it was several hours and they all worked great. They seem sturdy and were easy to set up.

### ⭐⭐⭐⭐⭐ Perfect for a Glow Party
*by G***E on June 24, 2025*

I bought these for my classroom glow party and they were very bright and effective. Yes, they will get a little bit hot, but that is to be expected. I kept mine on for hours and they ended up doing just fine. Just don’t leave them on unsupervised.
