    PAT: Metal framed lightshade on class 1 ?

    Conventional metal framed lightshade on a class 1 luminaire. (Luminaire itself is all safe). Lightshade insulated from brass bayonet lampholder by plastic diameter/size-reduction ring. I thus define the shade as double insulated part, - and it's OK for it to float unearthed?
