Work Horse ballasts?

Hi,

I would go with the 55W PCs - its a bit safer and more conventional.

However, 80W NOs (aka 4x Overdriven NOs F32T8s) can blow past 55W PCs. And tubes are cheaper ($4 for T8s vs ~$?? for PCs). I think the PCs are $15...not too sure about it.

55W PCs are rated closer to 5500 lumens. They may be 8000 lumens in the first 100 hours...but they drop off pretty fast. Overdrive 4x are 6500-6800 lumens @ 80W.
