Eye Iwasaki 40W clear mercury lamp

another lamp I have had in my collection for many years (I have recently been re-organising my lamp collection so I am taking the opportunity to upload some of the lamps which I got years ago but never did upload for various reasons)

is this lovely Eye Iwasaki 40W clear mercury, this was the smallest rating of high pressure mercury lamp made (outside of the 30w~ arc tube from a 100W self ballast mercury lamp anyway!)

I think Eye was the last company to make dedicated 40W and 50W mercury lamps, 40W mercury lamps where never a thing in Europe, but where a thing in Japan and the US, however in the US, most lamps of the past few decades have just dual rated 40W/50W (I say never a thing in Europe, however Eye did list 40W in their European catalogs, but even this lamp came directly from Japan from another collector, and im not aware of any European manufacturer offering the 40W size)

in typical Eye fashion, it is extremely well built and a lovely little lamp
