Fluorescent Light Fixture Size (with same bulbs)?

Quick question that stumped me...

Is there any reason at all to buy a bigger fixture (for instance, 24"x48" instead of 7"x48") that uses the exact some type and number of bulbs?

I see 2xT8 wrap around fixtures of 2 or 3 different widths (identical other than width.. same reflectors, etc), and aside from the two foot ones that fit in between drop ceiling tiles, is there any reason for it? is there any difference in light output/dispersion on them by size? Can't understand why anyone would want a bulkier light with the same light output....

Thanks,
brian

Cost, looks, replacing an existing fixture of the same size. There are lots of reasons. As for the light dispersion you would have to go to the manufacture for a photometric diagram.

A fluorescent fixture where the tubes are spaced more than an inch from surfaces behind them and from each other and that you have lined with aluminum foil will deliver more light with the same tubes compared with a fixture where the tubes barely fit in the space provided.

Different styles for different folks.

Only suggestion, ditch the florescent concept and go for LED. You will not regret the change, florescent bulbs are old tech.
