Flush downlights preferably fitted with LED lamps are very good for kitchens. You just need enough of them to avoid shadows.
They are a bit of a faff to fit. Depending on how many, and where they're sited, The usual thing is to work from the kitchen rather than go upstairs and dig up a load of floorboards. If access is possible from above, then it's simpler. If not, then there will be a few access holes in the kitchen ceiling to get the cabling through the ceiling joists.
