When we were building the granny flat we had to meet Title 20 – which required a certain percentage of CFL bulbs that specifically did not have the edison/screw in base. We bought the cheapest fixtures we could find.
We got our inspection, then changed out for normal fixtures – and put in screw in CFL bulbs.
Lamps Plus had a whole catalog of Title 20 compliant fixtures – but none in the store… You had to order them. They admitted most folks did what what we did – ordered cheap ones, then swapped for more stylish fixtures. At least we stayed energy efficient by putting in CFL to the replacement fixtures.
