Urbis z3s are quite a rare lantern in the uk, I only know about the ones on the M25. They have a aluminium front canopy, and they have a plastic back canopy held on by a plastic head grub screw. They’re also known as the Schreder Z3 in other countries.

M25

These urbis ZX3s are on the m25. They are on 14m columns and they run on 400w SON lamps. Unlike most stretches on the M25, these have their own photocells.

Here is a bit of the stretch of the m25 with the urbis Z3s, some of them have no bowls, and a bit further down, there are quite a few dayburners.

Here is the bit with a few more dayburners, the one closest to the photo is Dayburning and it has no bowl, and the one further away from the photo is also Dayburning.

Here are the some of the Z3s at sunset.

Here is a column with a slightly leaning bracket, the lantern on the left is a Philips iridium, and the Z3 on the right has a smashed bowl (not easily visible in the photo) and it also dayburns!
