Is it feasable to have recessed lighting installed in the soffit in the kitchen and over the buffet? That would eliminate the soffit shadow, brightening the area considerably.

Thanks. electrician says no. i do have under counter lighting which helps.

You could a ceiling mount in the 2nd picture in the kitchen area but not over buffet or FP

If you can't use recessed lights, I'd use a large, bright, semi flush fixture for the kitchen where you need a lot of light. You could consider using the same in the dining area on a dimmer, and then just use floor and table lamps in your space near the fireplace.

Be sure you choose good bulbs for each of your purchases. I have found 4000LED bulbs in "daylight" provide the best light in my kitchen and adjoining dining area.
