Recessed lighting can serve more than one purpose. This group of products can be energy efficient, provide general lighting or accent your favorite art work. Today recessed lighting fixtures are designed so they allow a minimum of air to pass from the joist or attic space into the room they light. In addition to this the finish or trim that is used can block even more air which will make the whole fixture as close to air tight as it can be. Couple these 2 items with an energy efficient light bulb and the package is complete. Good looks and energy wise.
When you want to accent walls or a specific piece of art the recessed fixture lighting can be a first choice. Not only is it cost effective but it will do the job without any effort.
