Yellow mottled glass Lamp

I looks 1930's to me,and has a large screw fitting but would like to know more about it.

The label gives it away that it's a bit newer.

The CE mark was introduced in 1985.

Trident Manufacturing Ltd. was operational between 2003-2008, and formally dissolved 2011, so it will date to somewhere between the first two dates.

The glass will have been imported from China, perhaps Czech republic, and might have been put together by Trident. But probably not.
