so, with regards to UV... UV doesn't penetrate glass very well does it ? WikiPedia:
"Ordinary glass is partially transparent to UVA but is opaque to shorter wavelengths, whereas silica or quartz glass, depending on quality, can be transparent even to vacuum UV wavelengths. Ordinary window glass passes about 90% of the light above 350 nm, but blocks over 90% of the light below 300 nm"
So.. I'm not sure the guys with the UV strand of LED bulbs trying to get a sneak peak really was a valid test.

Disclaimer2: Oh, sorry.. didn't see that it was already mentioned / debunked.
