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 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 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 are awesome and turned the whole room into a fest.

These worked perfect to light up the party

I originally purchased a 4' 72w unit. It arrived damaged (cracked lens) because of the poor quality shipping container. The unit still worked. It also appears to be the last one in the universe so I did not return it. Fortunately, I'm an electrician and believe I can change the glass lens. The original unit was of such high quality, that I purchased a 3-set of 16" 24W units for another area. These shipped fine (but still poor quality container). All units are bright, easy to install, and meet/exceed expectations. I did not contact Onforu, but it would sure make things simple if they sent a replacement lens for their 4' 72W unit. You can't go wrong with the quality but take your chances with the packaging. Your products deserve a rating of 6 (out of 5). I give the packaging/shipping materials a 1. Beef up the packaging of your high quality products Onforu!

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!

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.

Really high quality lights for a great price
