What does Air-Tight downlight mean and why would I want to use one? - Sarah Gaines , 2009-02-27 15:28:47

Any air-tight rated downlight has demonstrated in an independent testing laboratory environment that it will prevent air flow through the fixture. This is important because it saves money in heating and cooling costs. Just as important, some state regulations are now requiring that new home construction use this type of downlight.
