This thread has just made me realize just how big of a scofflaw I am ....

As I remodel my house, I have mounted many light fistures. They're simple keyless lampholders, attached to surface-mounted boxes, with a cord grip and a pigtail. They pluginto the 'temporary' receptacles I have also strung around the place.

Yup; DIY luminaires. Not a single one is a UL listed assembly.

Do you think that maybe the NEC has gone too far?
