Found this on eBay and bought it on the spot !   https://www.ebay.com/itm/254340533012

Being that it looks like an "regular" HPS reflector bulb but is totally clear makes me wonder if it an engineering sample or proto-type or something .

Looks interesting...definitely not MV.

We'll see when it gets here !

Any news on this..? Only just seen it, looks interesting to say the least
