We are remodeling a kitchen and need help. I appreciate your input.

The kitchen is 8 x 12 L shaped kitchen with a 8' peninsula. The refrigerator (36 ") is on the 8' wall, and sink and oven are on the 12' wall. At the peninsula (across from the 8' wall)' we will have two pendants. The ceiling is 7 1/2 ft. My question is:
- how many LED recessed lights do we need
- 4 or 5 inch, I prefer 4 but do not know if these will be sufficient
- preferred brand
- how much over 24 inch sink
- how to line these up given the refrigerator is not counter depth

Should the aim in the kitchen also be 36" from the wall to avoid shade? How then does one plan light over countertops? We will have under cabinet lights, but do not know if these will be enough for counter light.

In the past, we had 4 6" recessed lights and a center fixture and the 6" were too bright.

We are also adding 4 LED lights to a 12x9 bedroom, 7 1/2 ft ceiling. Again, 4 or 6, and 36" from wall?

Thank you very much for your thoughts.
