Since I will be re-doing the wiring at my house, the contractor asked me to mark out the spots where I want my lights to be. Currently, the house is using flourescent lights, and I plan to switch to downlights (those embedded into the flat plaster ceiling - i do not plan to do those L Box and stuff like that, just a plain flat plaster ceiling).

I read somewhere that the rule of thumb is to have the lights 1m apart from the wall & about 1.5m - 2m apart for each light. Is there any truth to that?

Also, any recomendation on what lights to use/not to use?

I have a high ceiling living room that goes up to the 2nd floor (those who have seen the 1.5 story USJ house would know what I mean). Instead of using chandeliers, is there an alternative to iluminate my living room? Suggestions/share of experiences are very much welcome!

Many thanks in advance!
