1. Should a double 175watt mh light look brighter than a 260 pc fixture?


2. When MH lights get old are they not as bright?

1. Yes, The output of a MH will out shine PC watt for watt.

2. The output goes down and there is typcially a color shift as well.

Old Bulbs. As they age they lose brightness.

If the bulbs are old then they are probably faded out. If they are brand new, they will need about a 100 hours to burn in to their full brightness.

Will these bulbs work with PFO ballast? " Those are some good pictures"

Probably. Do you have more info on the ballasts? Maybe Dakar will chime in here. He could probably tell off the top of his head. I can probably figure it out, if I could find the right thread.

You could also send the e-bay store the question.

Be happy to toss my nickel's worth in...just need a few specifics.
Which ballast do you have? There should be a number/type on it somewhere... and what bulbs are you thinking about using? Probe start or HQI (single ended or double ended)?

Your ballasts will handle the bulbs Whoyah suggested without issue.

They should fire any probe start 175w bulbs.
