Power Factor Correction is probably not an issue if you only have a few Fluorescent fittings, and don't pay for your power on peak demand.
If, on the other hand you have a humungous fish room with several thousand fittings switching on at once, it could be a concern.
Domestic users do not normally pay by peak, but your power provider probably does.
Most power providers like to see PFC at around .9, and will penalise larger consumers (ie industrial consumers) for being lower by charging them more.
The lower your PF, the more power is consumed. It's all about VoltAmps and Watts.
This is dredging through long distant and easily forgotten theory in my brain, and I hate maths, so it's a rough outline of what PFC is about.
