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 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 are perfect uv lights easy to use and great glow quality

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!

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!

Really high quality lights for a great price

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.

Only downside is they run hot. After 30 min the entire case is above 108 degrees F according to my thermal probe gun. Not a good idea for bedrooms or any medium size room unless you have vaulted ceilings. Plenty bright, they don't use an efficient bulb. LED doesn't put off anywhere near this much heat. You must use the mounts because they will leave a mark on whatever you place them on, they are too hot to hold after 2 hours. Great coverage, I'd say they'll work with a 18x25 room no prob. You can go larger of you don't need it to be too bright, like a skate rink or dance floor. They might be intended for commercial use so pardon my heat comments if that's the case.

Great black lights, however I lowered the review due to the fact that they get so hot to the touch!
