I'll leave an update here for anyone exploring this in the future.
LED strip used is SMD2835 120LED 24v with plaster ceiling aluminium profile.
The brightness is definitely sufficient, just the LED strip alone is brighter than my dowlight+eyeballs combined.
But please do note that if you want to use this set up, aluminium profile needs to be more than 1cm depth so that you don't get dark spots from the LED strip. Or else, you'd have to go with COB LED Strip which is lower in brightness but won't have any dark spots.
