The message
from "Mighty Magpie" mighty.magpie@home contains these words:

Hello, I want to obtain two uplighters for my kitchen. I would like to get
some which resemble half a cup, stuck on the wall but it seem that the ones
which are generally available, are all too wide. I would prefer them to be
about 180mm to 210mm long (7 or 8 inches)

You'll be lucky. A GLS shape light bulb and a socket for it to go in are
about 6 inches. Leave a bit of space so it doesn't get too hot, plus the
thickness of the ceramic and you're over that already.

How about some of these?

Pay no attention to that man behind the curtain.
