“Air-sealed” can light retrofit vs. Tenmat cover in attic?
I’m planning some air sealing work in my attic. I’ve got a bunch of recessed can lights to deal with, and I had been planning to use Tenmat rock wool light covers on the attic side. This would involve caulking (say, Tremco acoustical sealant) or foaming to seal the Tenmat cover, plus taping up any cuts to allow for electrical wires, etc. After first going into attic, pulling back existing insulation, sweeping the area clean, etc.
Now I’ve seen some LED retrofit lights that are supposed to be air-sealed, e.g., Nicor’s Maxcor DLR56. It has a solid face and a gasket on the back side of the flange. It’s basically a plug-n-play replacement for the current can light, except that it’s a) LED, b) air-sealed (?), c) white, instead of the yellowed plastic of original build. I can probably replace these in a minute, from the relative comfort of my living room, instead of working in the attic.
So, can these retrofit LED recessed down lights (90+ CRI, Cree LEDs, etc) actually eliminate the need for the attic light covers? Am I duplicating efforts to do both?
Thanks for your thoughts.
P.S. I’ve tried to go for higher temperature lights (e.g., 5000K vs. 2700K color), on the theory that anything approaching natural sunlight is better. Alas, I appear to be conditioned to prefer soft white that approximates incandescent. In your experience, is there a big difference between 2700 and 3000? Which would “old folks” likely prefer?
