Ontesik Black Light Strip, 40ft/12m Flexible UV Black Light with LED kit, 720lamp Beads, 12V UV Black Light, Indoor Dance, Bedroom Decoration，Stage, Birthday, Wedding, Dark Party,not Waterproof

Bought this for my curio cabinet to light up some Uranium glass.Brightness is perfect. Great length for the price. Works great. Was easy to use/stick. I think the adhesive works pretty well. I would buy again if I needed more.

best type of blacklight LEDs - especially for blacklight posters , 20Ft for less then even $20 is a steal to me, because these lights shine with real UV.

Easy to install. Just make sure your mounting surface is very clean. The prep work to get these to stay is the most important part. It’s two sections of rope light and you’ll want to tape the connection between to two pieces as the plastic connector seems like it will work loose over time. Installed on a 26’ travel trailer and started at the half way point on the front and went to the half way point on the rear.

While the lights were a little dimmer than what I expected, they still work well and are the right wavelength to cure UV resin without and problems.

Love this string of lights

I’m really glad I went this direction! I wanted to create a display shelf, and I was initially looking at regular black lights to put on the shelf “ceiling,” but these popped up in my search results. Great price, came with adhesive so I wouldn’t have to wonder how I was going to install it. Decided to give it a try. Works like a dream! Does exactly what I wanted it to and looks super cool! Even though I only lined one little section of shelf, it gives off enough light that things were glowing on my couch across the room. The adhesive is nice and sticky, and I was able to reposition the strip before pressing it down completely. Would definitely buy these again.

The light emission bandwidth is too broad it needs to be narrow bandwidth right around 395 nm or 365 nm. There’s a lot of excess blue light in the visible spectrum that detracts from the fluorescences of my uranium glass.

I ordered these lights to make a couple of curing stations, and they work great for curing UV resin! The only thing I really have to note is that if you order different packs, your strips may come in different brightness "shades" of light. If this happens to you, don't be alarmed--I'm pretty sure this is because of the different colored adhesive backings that the lights come in, but to my knowledge it does not affect the actual wavelengths these lights produce, nor does it affect curing. Also, be careful if you are adhering the lights to aluminum foil or anything delicate like that because the adhesive backing works almost too well and will take a chunk of the material with it.
