Sounds to me like we mean the same thing when we refer to the controller, except that in this setup, it is a separate device from the power supply, connected between it and the LED strips. It's the white box pictured in the link; ignore the remote.

Thank you everybody, for your insights and suggestions! Especially to Alec, that is great info. The controller box is one of these: http://www.dx.com/p/44-key-ir-remote-controller-for-led-light-strip-white-152672#.VdLRYm7speU. I did a reverse image search but couldn't immediately find any more...

Hi everyone. I have a question that I would be grateful to receive your insights on. In our bedroom, we have a LED strip running from a typical 12V transformer. We turn it off at night using the controller box, which is in between the LEDs and the transformer. The thing is, a couple of times...

That sounds like a useful approach. The packaging says "working voltage: 12 Vdc", and "Input Voltage: 100~240 Vac". Does that include the needed info? I tried a bank note that's supposed to light up under UV, and it doesn't, but then it didn't under my 'real' blacklight either, leading me to...

Well, I think I solved my problem. I took some of my reactive items to a store that sells colored LED strips, and found that theirs had the same effect. Combined with the various datasheets I've read that show fairly selective wavelengths to be the standard, I think that most likely all blue...

That's a creative angle - thanks for the idea. S'too bad it's just nearing the end of fall here. I'll have to see if I can catch a straggler.

Interesting. Does that give me anything I could use to tell the difference? Anything I could reference for affected colors, maybe?

Thanks again for the help, all of you. However, I'm getting conflicting and inconclusive results with these approaches. Every SMD-5050 RGB LED datasheet I've found online lists focused wavelengths well out of the UV range. The manufacturer (and datasheets) specific to my own strips remains...

I'll try it with the green ones on, thanks for the tip. I'm not in the US so no dollar bills available, but I'll try the petroleum jelly. Thanks. =) That's interesting info, thanks. Where would I start looking for datasheets on a string of leds? I live in a european, non-english speaking...

I recently purchased two strings of RGB LED lights, the kind you can set to all sorts of colors by combining red, green and blue in various amounts. Unfortunately, I strongly suspect that the blue and green led-pieces produce light that is contaminated with UV. Various UV-reactive things in...
