street light problem

[zone77]

i was recently asked to sort out a street light that wasnt working and found the light sensor was faulty so changed it and swapped lamp. now the lamp strikes on but doesnt stay on. is there a way to test for faulty ballast or choke? not very experienced with this stuff.

is there a timer on the sensor that you can adjust

 

[zone77]

no timer

If the light was flickering and flashing for a long duration before failing there is a possibility it has damaged the ballast, what kind of lamp is it?

 

[benji]

some lamps have integral igniters

As benji said did you chech whether the was a E or I onthe lamp before you replaced the lamp as some have an external ignitor and some an internal ignitor.

If you replace the lamp and it still does not work it is quicker to change the ballast and ignitor rather than mess around swopping each until it works, it may be cheaper and quicker to change the whole fitting

I done alot of parking lot luminaires and if ballast or ingitors is not working after a simple lamp repalce I just swap the whole kit in and be done with it due most parking lot luminaire are mounted pretty high 10 to 15 meter up typically recentally before I went to France the last one I done is replace 70 lamps , 18 ballasts all of them wired at 277 volts triphase supply to handle the whole lot.

that lot took me most of nite to replace all of the lamps { the reason due the parking lot is empty so I can move quicker instead of jocking around with parked cars which I hate the most }

Merci,Marc

Another good reason to replace ignitor and ballst together is you have more chance of them being the same make and therefore easier to decipher the generally rubbish wiring diagrams they provide.
