Street lighting control

nElectric

Does anyone have an insight into how Councils control street lights? My client is a residents association in a private road just off a Lincolnshire County Council public highway. They have seven street lights in the private road, each appears to have a single feed to them and there is no (apparent) control box for them - it appears their street lights are fed from the public highway (unless I am missing something). In the middle of the night the public highway lights get turned off, but those on the private road do not.  I have been asked to quote for providing a timer(s) for the lights  in the private road - in my opinion the installation cost and inconvenience in the event of power cuts does not justify this approach - am hoping they can be included in whatever switching on/off the Council do. Any pointers please on who to speak to to see if the private road lights can also be controlled by the Council?

    Good morning,

    First time poster here but as this is in my wheelhouse I'll stop lurking and offer my opinion.

    There are a number of ways to control lanterns such as this one and I can see by the replies that CMS control, timers and photocells have already been covered. It is likely that given the description of the switching regime 'part night' photocells are being used here for the public highway lanterns and standard photocells are being used for the private road. As already covered, part night photocells differ somewhat from the standard photocells (on/off) as they turn off for a proportion of the night to save energy.

    With regards to introducing a Sangamo timer in the base of the column I can confirm that this is very common, but perhaps more labour intensive in the long run due to varying ambient temperatures affecting a potentially sensitive timer PCB. Most electronic timers have a battery back up so power cuts won't necessarily be an issue. Historically, manual operating din rail mounted time clocks were used in column isolators (such as the Hager EH010), but these have been phased out over the years and replaced with digital products.

    Many street lighting manufacturers will offer you a design and price for a small prewired isolator with 2P switch, fuse, timer and/or contactor to replace the light grey (Charles Endirect) enclosure at the top of your column base in the photo. As it is, the enclosure currently there is only equipped to house 2 standard din rail devices, therefore a new 3 or 4 module enclosure will be required for connection into the DNO cut out.
