I'd imagine that depends on the quality of the shade. Don't you think

I propose nice to look at sockets and lamps instead. Brian

Trouble there is that they aren't very nice to look at, and if you can
look at them then they aren't bright enough to illuminate a large area
very well. I thought the idea of a shade was so that yuo couldn;t see a
really bright bulb and that the light got diffucused by the shade which
could also add a bit of colour.

the original reason for calling them "shades" was that they shaded certian
places from the light. Sometimes they act as diffusers, too.
