In the process of renovating a new property for my garage.
The garage is 22x22. I installed 2 8ft fixtures with T5HO bulbs in the middle of the garage and 4 4ft fixtures at the back and 4 4ft fixtures at the front. The T5HO bulbs are super bright, No shadows at all
right now its a 35x50 just one area. it has 4 450 watt metal halids so there are shadows all over the place. And it is costing alot just to run these 4 a month. Looking to change out with maybe 20 dual light 4ft T8 fixtures and 5000k bulbs. it would actually lower the operating price and distribute the light all over. They will be hung right at 13 ft from the floor. I was thinking 4 runs of 5 lights or even using 29 fixtures and doing 4 runs of 5 then 3 lights in between each run. I could run them all on one switch and one run of 12-2 that is already there just branch off it.
