I live in a building that was convered into lofts about 20 years ago. In the kitchen there are four potlights. The potlights have 6" openings. The bulbs look like mini-spotlights (I assume they and the potlight housing units are quite old). There are no baffles/covers on the potlights, so you can see around the bulbs into the casing itself. It is quite ugly. I would like to update this look. What is the easiest way to accomplish this? Can I simply purchase baffles / covers and replace the bulbs with something sleeker that provides better light? Thanks in advance.
