yup for your downlight maybe you also can link it using the 'IC' box..e.g using the same 1 switch..on 1st..light A on..then again using the same switch other light on or both row on...walaaaaa...

chk the detail on the bulb itself..ado china mali lor..

also what theme u want it to b...cozy or bright....some color bulb makes your wall color dull...

plus chk the type of the bulb...screw or plc....spiral or u type....

chk wther your DB board can cope with amount of the lights if all on...takut trip or fire hazard..

chk the wiring also using the 2.0mm ?...takut they curi curi using the thin 1...

you can have the dimmer energy saving but all comes to the budget lor...

or you can also option using the remote light control...e.g 'TOMATO' remote control...so wisely plan your wiring...like most lighting shop do..but makes you a 'Potato Coach'..hehehe...
