I'm flirting with the idea of lighting this 32 x 21 foot area with recessed lights. I was thinking 6 inch cans with 65 watt bulbs in them. I plan on having a drop ceiling. This lighting place tells me I need one every 4 feet! Thats around 40 6 inch cans.. For some reason I'm not thinking this is correct.. Can someone please give me a suggestion. Thanks.
