carriej These look like 6" cans with Black Alzak trims. Juno makes these. What is cool about them is if you use a smaller PAR30 lamp in them and a Black Alzak cone trim you won't see any surface brightness at the ceiling when they are on. It almost looks like they aren't even on (even though it is bright below). Cool trick to make the light fixtures recede in the evening.
