I have a mercury vapor light that turns itself on/off intermittently at night.

I called the electrical contractor that installed it and thought I just needed
the bulb replaced. The owners wife who answers the phone said it could also be
the ballast.

What are the prices of these parts?

Would it be more economical to have them install a new one?

Any estiguess as to labor time? It's about 15' up so they used a ground ladder
and one person to install.

When I purchased it from an electrical supply place (as instructed by the oelec
co owner) I noticed they did not appear to be real durable...

Any ideas as to what a modern alternative would be?

Thanks all!

Change the bulb. *Cost around $10.
I have one of these lights, the bulbs flciker when they are getting
weak. *- Hide quoted text -

It's usually the bulb. Metal Halide fixture will have a ballast
transformer and a capacitor. High pressure sodium will also have a
starter. The parts are pretty cheap online. .
