Bought most of my lights from No.1 Lighting in Geylang - price n service won us over. The uncle was not out to extort, and even advise us against certain lights which we absolutely loved but was way out of budget.

L: 2 of these (with silver holder) for toilets
R: 2x13W Square downlights (x12) for living room

With 2 more cheap lights ($3.90 ea, bulbs were expensive thou) from Ikea for store and service balcony. Ikea is quite a gd alternative for cheaper lights. Designs are pretty decent and value for money as well. Downside: can only use Ikea housebrand light bulbs, which is quite pricer as compared to their lights.
No fanciful drop-downs for dining or anywhere in the home. We've yet to decide where the dining table goes n besides, maintenance is probably gonna kill my neck.
All in all, we spent $600+ (after bulk discount, n best of all NO GST!) in No.1 Lighting.

*Edited: My switches/powerpoint sockets were thrown in FOC by my contractor and I wasn't too fussy abt getting designer switches. As long as it's the 'big big' switches, I'm prefectly fine with any brand he provides. "Beggars cannot be choosers." :P
But nonetheless, this shop seems to be one of the more popular shops in forums for Clipsal and Legrand switches that I may take a 2nd look if not for the FOC switches.

Having shifted into our new pad for almost 2wks, there are a few things i would have reconsider or insisted in my next home building.
1) Double tube PLLs lights, 2x36W for each time i turn on them on. That's quite a thirst on electricity.
2) Wire fewer downlights to individual switches.
3) Single tube vs double tube downlights - latter drinks a lot more, but not necessarily brighter by a lot? Since there isn't any single tube downlights in my entire house, i do not have the necessary findings to validate this stand.
4) Table lamps and floor lamps would be my next buy. Bring a little coziness, esp in the bedrooms, instead of the normal PLL white lights on ceiling. Budget didn't allow us to have false ceiling/downlights in the bedrooms, so we sourced for alternatives for mood-setting ambience. A little more savings in electrical bills too as now we have an option to get energy-saving bulbs that goes as low as 5W!
5) would still insist on downlights (for asethetic reasons) and at the same time, lesser cleaning as compared to pendant lighting or chandelier.
