Blacklight so strong people got sunburn?

  This sounds to me like someone put in real UV fluorescent tubes instead of blacklight tubes, those things are dangerous.

    Cheap blue LEDs will leak the dangerous parts of the UV spectrum. I've had projects hit import snags in the EU because they got spot checked - the overseas contract manufacturer used parts which were out of spec.

  It’s not much brighter than usual, but it’s UVC, a higher frequency/shorter wavelength than what we are used to on the surface of the Earth. UVC reacts with (di-)oxygen to make ozone, so it’s blocked by the ozone layer. The smell is very distinct and it burns eyes and skin readily.
