table-top led's

Hi Everyone,

I cant seem to find any LED holder/bracket that would accomplish what
im trying todo. This is a little off-topic, its not specifically
electronic related, i just figure that with everyones experience in
electronics and components/enclosures, someone may have come across
something suitable.
If not, im going to have to design one and have it custom made, which
could get very expensive.

I need LED's mounted on tables - these tables are expensive casino
tables, so big messy holes are not an option.
What im thinking is something like a little saucer (to cover the
roughed up felt after drilling the hole), with the LED mounted in the
middle (perhaps with a lense cap), and this saucer has a threaded pole
(out side thread) about 10cm long, so a nut can be used under the
table to secure it. (the wires running down the centre).

I have been googling for ages and cant seem to find anything suitable
to mount to a table top. If anyone has seen anything like this, or has
any ideas ...

Thanks again!

Alex.
