Colour temperature, dimming and the small fittings
Keep every fitting on the same white
Mixing colour temperatures is the fastest way to make good joinery look cheap: a warm ceiling against a cold strip under the overheads turns a white door two different colours. Choose one temperature and specify it across ceiling fittings, under-cabinet strips, in-cabinet lights and pendants. A high colour rendering figure matters too — it is what lets you judge whether meat is cooked or a benchtop sample is grey or beige.

If you want dimming, say so early: the fitting, the driver and the switch all have to be compatible, and retrofitting a dimmable driver into a closed cabinet is awkward work. The small fittings are worth the same forethought. In-cabinet lights behind glass doors turn a display cupboard on at night; a toe-kick strip washes the floor and makes a narrow galley read wider; a single light inside a walk-in pantry, switched by the door, saves opening the door and standing in your own shadow again.
