We are starting reno on our 1987 era kitchen. It currently has a track light fixture on ceiling. We would like to remove track and replace with 4-6 can lights. Kitchen floor area is 10x10 feet with ceiling approx 9 x 9 feet due to soffits. How many lights needed? We do have undercounter lights and one can light already in over the sink. Plan to add two pendants also over bar area. Thanks for ideas.
