A recessed light in the ceiling probably wouldn't work well - it would either be behind someone working at the sink and cast a major shadow in front of the person or it would have to be so close to the upper cabinet that it would look like an afterthought, assuming it didn't interfere with the doors in the upper cabinet.

I think either 1 or 2 puck lights (or similar) mounted under the shelf or the LED strip CooknCarpenter mentioned would be better.

I have puck lights under my cabinets - the light itself & wiring are hidden by light rail:

I have no advice, but just have to say that is one freakin' awesome kitchen.

LED light strip. Look at the hafele loox for ideas. You can recess or surface mount them. There are also LED pucks if that is your preference

Good luck!

Maybe I'm not seeing the pictures right, but it looks to me like if you put anything in that little cranny, the shelf below will be shading more than half the sink--probably not what you want.

another vote for LED tape which would fit nicely in the cranny :)

I agree with Megan. Won't the shelf below still create a shadow over the sink? By all means put a light in there for fun, but I'd want something that shines unimpeded over the sink, like a puck under the shelf, if that's even possible.

Search on "under cabinet task light" you will find that you have literally hundreds of choices.

Any lighting put in the nook will be decorative only - not functional (as was pointed out by a couple of people). That's why I suggested pucks (brighter than most strips) under the shelf.

If you want to put decorative items in the nook and then light them (similar to how a display case is lit), that would be nice, but it would not give you task lighting at the sink.

Another option for that nook is a plate rack - either for decorative plates or every-day plates.

Thank you. I wasn't adding task to my search. http://www.junolightinggroup.com/attachments/images/content/SpecSheets/I1_7_0.pdf This might work.
