Happy to have found them!

Our lights had been flickering off and on for the past couple of years. We tried to eliminate possible causes by changing our the meter and even having the street light replaced with a sodium vapor lamp.
We thought that was the culprit!
No such luck! That is when I called Benchmark; and while they found nothing wrong on our end, the service was fair and professional! I will certainly keep them in mind. They are prompt as well.
It turned out to be the power transformer. :)
