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.

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!

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!

Got these for our Vacation Bible School and they were perfect!!!!Very lightweight and a perfect size to fit in our Church Windows. The kids loved the effects!!!

I went with the led lights over fluorescents bc they're much safer for your health and don't get as hot. If using just one, the brightness isn't as good as the old florescent bulbs, but they're also very small. I put one on each wall and it covers the entire room. They make things glow so vibrantly. I'm very happy with my purchase.

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.

Bought 4 have had them for a long time 4 or 5 plus years two finally just burnt out two still work perfect. Id say good little lights for what you pay. Happy with yhe time i got.

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!
