Bolton Council have started a low wattage SOX/SON replacement scheme. This has seen LED lanterns and in many cases on concrete columns sleeves. The new lanterns are controlled by a device that looks like a large white photocell, but given all lamps come on a split second after one another it must be some sort of CMS.
The council use a Lucy Zodion VIZION system on the larger lamps so I wonder if this is an extension. There appears to be no new collectors fitted though.
The controller has a sticker on one side. Of the 3-4 hundred installations there are a couple of failed controllers which dayburn, and a couple more lamps that fail to light. Where this lantern has been used as a casual replacement the lantern is fitted with a standard cell.
The only thing i could find on Google was this
