Hi, there is not enough context to your inquiry. What is your ceiling height? Is there a soffit over the sink where lights would mount? How close are upper cabinets to either side of the sink area?
Posting pictures would help illustrate. What is the style aesthetic of the space, and of existing lighting?

So sorry I must have got interrupted and then accidentally sent this! I will try to update my question later when I have time to upload some pics. Thanks again
