I also have a new 81 X120 pole building that has white steel walls with the bottom 4 painted yellow for contrast and white steel ceiling at 14 high, this building will be used for dog agility training. The end of the building first 16 X 81 feet will be seating / viewing area 2 bath rooms and a utility room each of these rooms will have its own fixture with the remainder 104湛 81 being dog running area the floor is green soccer turf. I have looked at various lighting scenarios and I initially wanted 18 six bulb T5 fixtures 6 rows of three but the fixtures are pretty expensive
So I have been looking at 20 four bulb T5 fixtures 5 rows of 4 and two over the running area and two 2 bulb T5 fixtures at the end seating /viewing area
Im thinking T5 over T8 because they are more efficient and put out even more light
I think this should be plenty of light ------any ideas for places to purchase these fixtures ---ie best price for the fixtures with bulbs and straight prong plugs, no motion, no emergency ballast I have been searching all over and the prices are nuts
