street lighting help

[telectrix]

got a job on, a park homes. 9 street lights with obsolete SONs. several failed, either lamps or control gear, and can't get replacements, so decided to go for LED alternative. can fit a E27 base and sourced 40watt LED lamps to fit. problem is that these lamps are not compatible with photocell switching according to supplier's research. anyone know of a solution?

Does each post have an individual photocell or is there 1 for all?

 

[telectrix]

individual. top of post is like a translucent bucket with a hat on. photocell is on top of the "hat"

Can't understand why the lamps would not be compatible with photocell switching, what's the difference? We regularly retrofit old SON fittings with britesource corn lamps with no issues.

What about bypassing the individuals and putting a photocell near the DB and have the photocell switching the coil of a contactor.

wholesaler gotonto supplier and was told the LEDs i was interested in ( 40watt, E27 base) were not compatible with photocells. i've had this before with a couple of 10watt floods.the photocelss will not switch off.

not economical. 7 lights fed from 1 DB via timer. other 2 from a different source.

I wonder why, surly the photocell switches an internal relay? Maybe in needs a sufficient load, I would be trying one, you may be trying to solve an issue that doesn't exist?

Or find a lamp which is compatible?

Could you replace the whole head with something like this, photocell is an option

not with the existing design. as previous post, the light is basically just like a transparent bucket sitting atop the pole, with a metal cap like a minature dustbin lid.

looking at these :
Search results for: 'led corn' - https://www.lampshoponline.com/catalogsearch/result/?f=40watt+led+corn&q=led+corn


thinking 40/60 or 80watts

I know the fittings you mean, they have a centre cap that you unscrew and the whole lot lifts off.

Those lamps look much like the britesource ones.

What about these, plenty other styles aswell.

[telectrix]

then brightsource look OK. 40watt E27, 60/80watt E40. as long as they work with the photocells, that'll do.

That is weird, the LED wont switch off??? A switch is a switch aint it??? Puzzled! I've put lux switches with LED no probs.

We've always used the 100w ones so a larger load, maybe that's why they work with the photocell, you would need confirmation on the 40w ones.

The lanterns described sound very much like the old Thorn 'Gamma 6' type. Do they have to all be on all night Tel or could you bypass the PECs and fit individual decent quality PIRs to each column ? This could be a very 'green' solution.

 

[telectrix]

needs to be on all night as it's basically street lighting. residents need to see if anyone's about .
