Works great
For RGBWA+UV WS2811 LED module
I bought this out of curiosity to play with one of these modules, and ended up using it with Pixelblaze in a Halloween Jack-O-Lantern. It worked great! Strobing the UV does add a cool effect to most colors, as mentioned. It's very bright.
I will say that something about this wavelength is a little different than fluorescent UV tubes; It seems a little more "light blue" and visible, but that's not related to this module, it's true of most UV LEDs I've seen.
I appreciate the thoughtful approach to heat dissipation.

We're glad you enjoyed it! There's now a new version with an aluminum PCB for even better heat management.
