One of the layouts at Pecorama has a 24 lighting scheme. It's very effective. I think there is a German company that does a day / night lighting system for model railways but it isn't cheap. I think it might have been mentioned in a Nurnberg toy fair report?
You can buy "star light" lighting kits. They consist of bundles of optic fibre of differing lengths and a single light source. The idea is that you feed them through your false ceiling. These definitely are not cheap. Here's a link to a site selling them. I have the site bookmarked because I am thinking of installing a lighting track in the loft and this company has a fairly wide range.
