Bathroom light fixture wire terminals

Okay, now I get what connector you're talking about. Here is a link to Orvac's catalog with several different sizes. I'd still use a wire nut, it would be bigger than the crimp fitting but what the heck.

Thanks to rj for the URL.

I didn't compare prices but the specs for the connectors on ZORO is far better than on Orvac. Orvac is a store for the trades and customers usually know which size they want. I seldom know, so I bought a selection by visual assessment at the store when it was close to my home.
