Why Are My New HPS Bulbs Dimmer?

KarenMN

Replaced my burnt out 600W Gavita HPS bulb and found that the new one was much dimmer. Thought it might be just the new bulb, so tried another new one from a different source, and it's just as dim.

Could this be a problem with the ballast? It's only a year old. How long do ballasts last?

Voltage here may have been cut by the power company due to high demand. Could this cause it?

How can I find out what's wrong?

Any ideas greatly appreciated. Don't know what to do now.
