What is wrong with the CFL, may I ask? Is it a matter of looks? According
to the link it will last longer than an LED. LEDs claim 25 years, but that
is based on three hours of use per day. A dusk-to-dawn light will average
12 per day, so an LED will only last 6.25 years. And will be getting dimmer
as the years progress. That CFL one claims seven years.

Yes, it's looks.

A pancake style LED without the photocell would also work since then a
separate photocell socket would not lower the bulb too far, i.e.

I dont understand this thread, (but have not read all of it).

Anyhow, you can buy a photocell that attches to any electrical box. Just
screw it into any hole on the box, and wire it as the instructions tell
you. Problem solved!
