30pcs 12 Volt 5mm UV LED Lights Emitting Diodes Pre Wired 7.9 inch DC 12v Ultravoilet LED Light Clear Lens Small LED Lamps

Works great on the metal art that I installed it on

I've used different LEDs over the years. What I really liked about these is they really do look like the color described. I ordered orange and they are really a nice color of orange. I am very impressed by the the finished product. I tugged on the wires when I installed them and they held. I've had other products that gave up the ghost when you stare at then too hard. Really good price and quality. I will be ordering different colors from the same supplier now that I know who to order from. Would recommend these if you need a bright tough LED that can take a little punishment for a tight instillation. Very fast delivery too. What's not to like? They are great :)

In the picture, 12 volt on the left, 9 volt on the right. There is very little visible difference in brightness or color between the two. There's certainly is a UV element to the color, but it is mostly blue.

Plenty of sets in this package and as long as you have the correct voltage they work great! I use them to cure the inside of my resin prints.

For those doing 3D resin printing, with 405nm resin, I can confirm that the UV 5mm does work to cure the inside of resin prints. An important step to prevent liquid resin from reacting with the outer shell of cured resin and resulting in a physical failure of the model. The two cracked models show what happens if you don't cure the inside of the prints. To test, I dipped a mini in the resin vat, let some resin drop on the tray and then set up the LEDs near the mini and the puddle. They were both non-tacky within 5 minutes. For connections, these LEDs already have a resistor and I bought the following power supply which has an adaptor with screws for bare end wires. I twisted the groups of wires and put them in the adaptor. Plugged in the adaptor and I am set to cure inside models. No soldering, as you will see if you YouTube "resin curing snake". I only put in 5, but it's a 1A adaptor and the LEDs only use 20mA so you could attach a lot of them.
