i got my light fixtures from lowes. just regular sockets, theyre plastic and cost 1.25 a piece. the only thing is, they were in one of those "dont forget to pick this up" bins, i don't know if they put em out on the shelves. i looked for them once and all i could find were the expensive ceramic ones, i luckily stumbled upon these. I'm sure theyll have them, either lowes or home depot. are those kitchen/bathroom fans pretty loud though? the one in my bathroom is.
