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!


Best color, more natural light will be from a metal halide light.
The most efficient as far a light output will be a high pressure
sodium light but the light is quite yellow. I like the metal halide
lights myself.
