My buddy has a ton of 4 ft long 4 bulb light fixtures perfect for garages or workshops. $15 a piece. These are the fixtures only and no bulbs included.
I think he has some good 8 foot 2 bulb ones too if anyone is interested
They are open industrial types with no lenses. If by gangable you mean they get hardwired then yes.
Still waiting to hear on what bulbs they take though
