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.

### ⭐⭐⭐⭐⭐ Glow party must have!
*by C***R on November 7, 2025*

Worked great for a glow party and Halloween! These lights worked well outdoors and indoors. We bought black light body colors and my 13 year old loved it for her party. It doesn't get too hot in my opinion. I hope to use them for years!
