While I like test equipment, I don't think I could justify spending £1000 on a UVC meter to test a £16 eBay disco light.
Instead I settled on an Adafruit UV sensing module with onboard amplifier, and a piece of glass.
I'd say the results are fairly decisive based on a conclusion extrapolated from current LED construction technology, visually perceivable wavelengths and the UV transmission of standard glass.
In short. Many of the eBay "germicidal" lamps are a rather cynical scam, especially in the current global situation.
But hey... We don't call eBay China's dumpster for nothing, and to be fair, it does make dangerous stuff available to the technically adventurous that simply wouldn't be available from "normal" shops.
Here's a link to the UK source of the Adafruit module.

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
