Our kitchen is about 5m by 4m and has 14 jcc fgled dimmable 6's in the ceiling and then under cabinet lighting, it's arranged as:-
three lights in in row over front edge of worktop over sink - without these you had your back to the light and effectively cast a shadow over things by your presence - these are on a separate circuit
row of 3 in walkway space
4 lights over worktop L shape return into room
4 lights in walkway through to garage
The 4+4+3 are on a single circuit and come on after dark via a sensor as well as switch
undercabinet light on own circuit.
all of these are cool white which for some may appear very clinical
for me it is down to customer choice depending on whether they actually spend time in the kitchen cooking as opposed to using the micro pinger to reheat things and then practicalities of joist position
the kitchen is supposed to be a work room and as such needs decent lighting in my opinion.
prior to the LEDs there were 12 50Watt gu10's, 3 35W and the under cabinets - the lighting wasn't particularly uniform and the meter spun bloody quick!
