Earlier this month, American Electric Lighting came out with a new series of LED street lights called the AutoConnect™️. From my understanding, they're supposed to be a solution for street lights connected to a smart system. Operating times and dimming can be controlled via bluetooth or mobile devices owned by the grid. This will also be the first American street light with a bottom-mounted control receptacle. There are three sizes: Series ACC (compact), Series ACM (medium), and Series ACL (large).

That’s pretty cool. I like how they embossed the AEL logo underneath, kinda pays homage to the ITT era or their other early products.

The Aussie idea of mounting the photocell underneath is a good idea. It prevents birds from defecating on it and the sun wearing out the photocell, but it also has the option for a standard NEMA photocell on the top.
The "Photocell" on the bottom is not only a photocell, but a smart connectivity module.

not a BAD looking LED lamp
I wonder how long till we see them "in the wild"

 According to the document , the P/C is available either top or bottom mounted .

I wonder how long till we see them "in the wild"

Near me, it looks to be quite soon... these luminaires have been chosen for the City of Philadelphia LED conversion; mainly because of the fixture's connectivity / remote monitoring features.
