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

That appears to be a Mayflower node.

Ahhhh;

Having googled I agree.

I have not seen any submasters and they seem to have a short range.. of only 200m. Is that from each other or from the submaster?

There are a couple of isolated dayburners and i guess this would explain that!



Seems interesting they now seem to be running two different Radio Controlled Switching systems.

There was an interesting situation in Hampshire yesterday morning. Some of the street lighting was dayburning in a selective manner. It is as if somebody had selected for all medium-sized Iridiums to be switched on. It wasn't just all Iridiums linked to one master node, and it wasn't just all Iridiums in one town, as the scenario affected different towns several miles apart. I'm not sure if it affected the large 250W Iridiums, but the small 70W Iridiums were unaffected. And to reiterate, it was just Iridiums, nothing else.

May be linked to group relamping?

That's the only sort of thing I can think of, an inspection of main road SON lighting.

We have a days where the signal to switch off doesn't seem to make it to a portion of lamps, but the next day they operate as usual.

A power failure, or spike can cause lamps to come on mid day too.

A lot of central management systems from different manufacturers are now designed to be interoperable with each other, thanks to the TALQ Consortium.

Web Link

The idea is that if manufacturers produce compatible products, customers such as local authorities will be a lot more willing to invest, as it will take a significant element of risk out of the decision. No longer will street lighting authorities be ring-fenced to a single manufacturer in order to get what they want.

A recent example down my way is the use of both Mayflower and Harvard in Southampton on the South Coast PFI.

A quick query....

Can anyone advise what would happen if a lamppost with a collector was taken out by a collision....

A) At Night
B) During the day

i.e. what would happen to the lamps under the control of the Collector

I'm particularly interested in relation to the Mayflower/Harvard System

At day should be out,  at night dayburn? As they would be awaiting a signal to switch?
