Onforu 4 Pack 42W LED Black Lights, Blacklight Bars with Plug and Switch, Glow in The Dark Party Supplies for Halloween Decorations, Bedroom, Body Paint, Stage Lighting, Poster, Black

These are brighter than the others I tried. I placed them in the center of the ceiling facing out and it real lights up the small room. These are best I've found so far and a good value.

Perfect for My Classroom Black Light Party! I bought this set of 4 black lights for my kindergarten classroom, and they were PERFECT! We used them for our “Glowing Into 1st Grade” celebration, and just four lights were enough to make the entire classroom glow. 🌟💚💗🧡 One of my biggest concerns as a teacher was whether the lights would get hot, especially with little ones in the room. I was so happy that they did not get hot to the touch, so I didn’t have to worry about my students accidentally touching them during our celebration. The neon decorations absolutely popped under the lights, and the kids thought the whole experience was amazing. They completely transformed our regular classroom! Four was plenty for a full classroom, they worked great, and I would absolutely use them again for another classroom glow day!

These made our glow party come to life! Excellent quality and power. It does get very hot, so be mindful of little hands and placement. Would absolutely buy again.

Works well. Easy to hang. Decent cast of light.

Very bright lights the only drawback that I wasn’t aware of is that they get very hot.

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!

First of all, these UV lights look AMAZING. Even one seems to cover a pretty solid surface area and gets pretty good glow from UV reactive surfaces. Construction seems pretty great, all metal housing and feet for install. Finned on the back to help dissipate heat. Mainly chimed in with a review as I was initially a bit concerned about the heat, as it definitely feels warm and borderline hot to the touch after running for more than 15 minutes. After doing some research, I did see that it was pretty common for LEDs to get ~50-60 degrees Fahrenheit hotter than room temperature. Took some surface temperature readings after running for a couple of hours in a 75 degrees Fahrenheit room, and seemed to read right within that range. That said with that in mind, I'd be diligent about where you mount or place these things. All in all, a great purchase for less than twenty bucks a light, can't wait to get the other ones up!

These lights give great coverage.
