Trac 80w mercury lamp made by Luxten

Here's an interesting one which was the only one in the shop, I suspect this would have been bundled with a Trac-branded floodlight originally but was separated. Sadly the etch was already like this when found. I deduce this lamp was made by Luxten in Timisoara, Romania, due to its similarity with a Luxten SON-E/I lamp I have.
