Bedroom 1 needed another 2 nos 6 inch downlights

If you want hotel feel make sure the light bulb color temperature is 4000k or 3000k, the lower the warmer color

xphr3ak I meant the light bulb color temperature not the watt

Actually your living area need six downlights, 18w should be OK yet it depends on your ceiling height.

If you really want to make sure the brightness can ask if your contractor for lux meter to measure them on site for you.

I just realize there are yellow colour rectangular on the living area, is that a ceiling light trough?

if yes the 4 downlight lights at living should be ok when you open both of the lights at the same time.
