wat is ur kitchen size? wall height?

yup should be enough ...your kitchen cabinate have light under it?...max 6...but u can still format it lights on in pairs...or in 3's..or 4's then 2's..on together...that will save your energy as some times u don't need to on all at once..plus then use the 21 watt bulb lor...

mine dry - 8 X 19 using only 4pc (6" - 18watt)...on squence 1 n 3..or all on using the 'IC' box..

Hi light experts,

My living area about 14ft X16ft, height 9-10ft. how many 6inches (square) downlight do you think require? one bulb or 2 bulbs?
plan for plain board plaster ceiling only, no Lbox, and fan in centre.
Thanks...

hmm...urs 1 almost similar 2 mine...i'm planning to put only 5pcs 6" square with 1 L-Box...haven't install yet, but planning to put onli 1 bulb 1st even i bought it with 2 bulbs. need to try 1st, if not bright enuf onli will add another 1.if oredi bright then balance will put in bedroom as i haven't bought casing yet...

if 16' x 14' 6pcs square single bulb should be enuf, backup if not bright put deco lamp in center to cover it...it can act as a deco as well....
antzan, any comments? 

ahh...let me know the outcome after u install. will use urs a a gauge for mine!

Square type is more expensive than Round type, and some square can put 2 bulbs.
There are alot of combinations, square/round, size 4"/6", got cover/no cover, material aluminium/chrome/metal/stainless steel, with balast/no balast.

Functionality is more or less same, appearance is subjective. Of coz personally i feel square type is nicer and stainless steel is better too but higher price.
Practically and $$ wise, i prefer round shape 4" with no cover and no balast.

Reasons?
Round shape - Square shape is harder to cut the plaster ceiling compare to round (contractor might charged higher for installation)

No cover - If got cover, it is hotter, ur bulb life might burn easier. Harder to change bulb coz need to open the cover and normally cover will trap alot insects inside.
4" - Subjective choice coz i think 6" too big 

No balast - Generally light with balast will last longer but harder to change. And if u do looping wiring of few lights, one of the balast spoil, u need to troubleshoot which 1 spoil coz all the lights can't be turn on. If no balast it is easier to change urself if anything wrong but the life is shorter.

Material aluminium - Stainless steel too exp, metal will rusty, so i get aluminium.
For energy saving bulb, u have 3U or spiral light. 3U is cheaper price. Normally the wattage is around 18W-20W, of coz if u want brighter u can buy higher power.

Brands u got Philips, Osram and GE, of coz those cap ayam brands also. Personally i prefer GE becoz the quality is better but more pricey. It is harder to find in light shops too. Most will carry Osram and Philips. If u want save, buy Philips, this batch Osram really screw up in quality, the bulb burn frequently, ask in those lighting shop u will know.

Color, u got white, cool white and warm white. In laymen term, those yellowish light we saw is warm white, white color is white and cool white is like those Mc.Donald restaurant light, in the middle of yellow and white. I prefer cool white but the only famous brand has cool white is Osram so I give it a miss, unless u want try those cap ayam brand. Else, u might try to mix some white and warm white.
