It's bad enough that these lights are claiming to be germicidal when they are absolutely not. But the power rating of one was worryingly high for such a small light.

These also have the most basic buck regulator module in them with no output capacitor, which is strangely intriguing. I wonder if that affects efficiency without the capacitor to buffer the high frequency pulses.

Nice enough construction, but just pushing everything to the edge as usual. With the common tracking failure mode of these LED arrays when they burn out, there is a high risk of the exposed metal becoming referenced to the mains when the insulating layer burns through.

Research has been done into using blue and near UV light for sterilising purposes. Mainly because it's cheap and safer for humans. All articles I've read about it have basically concluded that it doesn't work well, but further research is required.
