The place to shop for lightings is at Balestier Road, that is, if you live in Singapore long enough, you will be familiar with the scene at this specialty row.  These shops import lightings from all over the world.  The cheaper models probably come from Taiwan and other sources from the nearby Asian Pacific region.

But interior designers order direct from the US, UK and Europe by the container loads for major development projects.  The lightings selected for “showflats” are quite impressive.  I have seen some like those from Hinkley Lighting.
