I was called out by a customer to replace three recessed(square)cans in a closet. These were incandescent and since there was a glass lens covering the lamp I changed the incandescent lamp to a CFL. The local AHJ told me that a 2-pin fluorscent lamp was necessary. I was told the village uses the 2008 NEC as thier code. The existing lamps meet 410.16(A) requirements does any one know if there is a requirement somewhere else in the NEC or NFPA that requires a fluorscent fixture that uses 2-pin lamps to be installed in residential cloths closets. I am confused?
