More info on lamp...it's in venezuela with 120v same setup as US. (well
almost). It is a 175W lamp (like a street light) mounter on a pole near
the
street. It is about 2yrs.old. The light is more green than anything I can
describe. (we do have some of themore yellowish lights in some areas, but
I
think they are sodium).There are some night that the light stays on all
night, and yet some nights, it stays on about 10-15 minutes and goes off
for
2-3 minutes then back on again....Then maybe it's 2 hrs before it goes off
again... or maybe it stays on the rest of the night.
Thanks for all of you input.



Sounds like mercury, they do tend to turn a bit more greenish as the lamps
age. Look at the arc tube, if it's blackened then the lamp is shot for sure.
Replacement bulbs are inexpensive and should be readily available.
