Urbis ZX1 (2006)

Lantern acquired in May 2007.

This lantern is another from eBay, and as a result is also brand new. There are several differences between it and my other ZX1 - the most obvious being that this one is finished entirely in black whereas the other is two-tone grey. With production of the ZX1 finally ceasing in early 2007 (in order to make way for the production of the similar ZXU1), my thought was that new examples would become difficult to find; therefore, I decided to purchase one while they were still fairly common!

A big box...whatever could be inside? The big text at the top of this page could be a clue, possibly.


A very well-packaged ZX1 of course!


The box beneath the lantern contained various accessories, including the photocell and lamp.


Every item had been wrapped in a separate piece of bubblewrap!


With the bubblewrap removed, the 'curios' can now be identified as a lamp, photocell and post-top adaptor. This is a 'VT60' adaptor which means that another adaptor is required for it to fit on 76 mm diameter columns - this is what the silver component beneath the VT60 is. A length of flexible conduit is provided to allow the supply cable to pass through the adaptor without becoming trapped.  This example is also fitted with a NEMA socket - something that my older ZX1s do not have. Although a space for a socket is provided on the canopy, in reality it is usually fitted in the position shown above instead due to the lampholder access being in the way. The four canopy clips have been done away with on this ZX1 as the two thumbscrews on the underside of the lantern were found to be sufficient.


This example has a shallow curved polycarbonate bowl. The positions of where the clips would normally be can be seen on the canopy.


The reflector in this ZX1 features a series of dimples above the lamp. The contemporary Schréder logo is visible between the two canopy thumbscrews; this being the parent company to Urbis Lighting.


Although the lamp control gear carries Urbis branding, it is identical in appearance to Philips gear, and is likely to have been produced by that company.


The ZX1 was mounted to a mini-column on Friday, 18th May 2007. It was then powered up. Although a SON-T lamp was supplied with the lantern, a White-Lux metal halide lamp was fitted instead, for variety.


Owing to the mini column being required for another lantern, the lantern went into storage; only being removed in late May 2018, when instead of being installed post-top, it was fitted to a wall bracket.


With this lantern positioned alongside its 1986 equivalent, we can see that the design has barely changed in the twenty-year gap between both versions.


In operation - the intensity of the lamp sent my camera slightly barmy!
