    Hi to all!

    I was able to buy a wonderful standard floodlight. The lamp is complete, but unfortunately the convex glass is missing. The inner width width is something around 200 mm

    Can someone who has an original glass measure theirs for me?
    - The depth of the convexity (preferably measured from the table to the maximum height of the glass when the glass is laying on the table) would be great.
    - Also the outer diameter would be fantastic.
    (- And maybe the thickness of the glass.)

    Thanx a lot
    Stefan

    The glass is exactly 200 mm in diameter, and the height is 30 mm.
    Thickness around 2 mm, but it's not easy to measure exactly since the edge is grinded flat, as you can see on the last image below.
    And the profile isn't a perfect round, as you can see, but rather a bit pointy.
    The glass in question is from this lamp, and there you can see the logo of the smoking chimney (some say a lighthouse...) for Jena in the centre of the glass.
