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.

These lights have proven themselves worthy. I’ve had them for a while now and I leave them on for hours sometimes days at a time and not a single one has burned out on me. I was skeptical of their size upon opening the box but sometimes big things come in small packages. They light up anything neon super bright. The lights themselves don’t look super bright but they make my art pop unlike some old fluorescent tubes I was using before. LED is the way to go for black lights for sure. They do get warm but I have handled them while on and they didn’t burn me or anything. Not saying to go grab one when it’s been on for a couple hours. The housing and mounts seem durable but not the strongest material either, which is probably why the don’t weigh too much. Never tried to submerge one or spray water on them when on to see how water resistant they are. Don’t recommend doing that either… I just know from experience that electricity, water, and myself don’t exactly mix too well.🤪 The lighting exceeded my expectations and I have a couple more for backup when one burns out. Overall good buy!

These lights are awesome and turned the whole room into a fest.

These worked perfect to light up the party

I bought these for a glow day classroom transformation. Loved the price of these but it didn’t transform the room as well as I wanted it to. Good for a small room but not for a classroom.

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.

These are perfect uv lights easy to use and great glow quality

Great for Halloween parties
