Lew,

could impose on your previous life one more time...

If a guy had 29 x 51 shed with 12' ceilings (white steel panels on
ceiling and walls, insulated) hoping for 80-100 FC maintained.

How many would you recommend ? and what layout ?

Use 1 watt/sq ft for estimating.

(29)(51)/(40)= 36.98 or 37 lamps.

So it gets down to any combination that allows even distribution of
fixtures.

What about 3 rows, 10 ft apart, along the 51 ft dimension, mounted 10 ft
high? (36 4 ft lamps or even 18, 8 ft lamps)

No consideration given to shelving, etc that might block out some areas.
