Let me rephrase this one .,,

you know paper towel tube if so it the same idea with tape make a small tube out of tape and put it on the photocell sorta like minitunnel that will reduce the glare of background and light source hitting the photocell and I will say not to compelety close the photocell up but still give some leeway to have it functioning properly.

Hope that clear up this one.

Merci,
Marc

Lamppost bulb


try this instead.

do this when it is dark

turn off the power to the fixture. put a couple layers of black tape over the PC. Turn the power back on. It should start up and stay on. Then, while it's still on, take the tape off and see what happens.

just out of curiosity; have you replaced the PC recently? How is the PC connected to the circuit? What color wire is fed from the hot circuit? What color wire feeds to the ballast?

No it is the original PC since it was installed in 1995 from the previous owner. I have no clue about the wires. I didn't open it yet.

Before you do this part below do Nap's part first that is a surefire way to test if you have bad photocell.

I did not get a chance to get a photo posted here however to get into the photocell in the post you will have to unscrew the whole luminaire off from the post it will be either set screw or a screw or other means to hold the luminaire to the post when you start to lift it up it may pull the conductors like weighted down.

For ballast in post verison you should able see a clip or other means to support the ballast.

The photocell may be above the ballast or below the ballast so it will varies a bit.

So when you remove it take it easy with the conductors and you may need a good flashlight to shine down the post to make sure nothing is hung up when you try to pull it out.

Merci.
Marc

I am looking at it now. The light turns on and stays on for about 2-3 minutes. Then it turns off for 1-2 minutes. I believe that it does this for 30 - 45 min before staying on completely the rest of the night.

What do you think it is. Ballast? If it was the PC I don't think it would act this way or am I wrong?

Would it be wise to switch away from a high pressure sodium light and switch to a cfl bulb instead? A hps bulb might be generating too much heat?
