UV Halloween string lights

[chirpis]

Hi everyone. I've seen people with battery-operated string lights that I'm certain are UV LEDs, and I'm wondering where I can get them. I've tried looking online, but I've only found one item for sale that explicitly says "UV" or "blacklight". There's tons of "purple" LED string lights out there, but those could be purple or UV, and I know I can't trust the photos.

Most LED's labeled UV are 405nm, emit mostly visible purple light, and aren't really a UV light. Look for products labeled 365nm, these actually emit most of their light in the UV spectrum.

405 nm is actually what I want.

Well then, go forth and purchase some 405nm leds - GL

I'm having trouble finding them in string form.

Would this be of any use? You would need your own power supply, but on the plus side, theyre dirt cheap!

I've thought about getting those, but I need to learn more about LED power supplies.

Just get some "purple" LEDs. They'll be in the 405nm range. The "UV" LEDs you'll find around are usually cheap 385nm+ LEDs or so.

However, i would like to learn in depth about LED power supplies techniques & operations before making a purchase. Can anyone help me out in this regard?
