Yea, thanks for the input. I've fixed a bunch of the fixtures simply by
replacing bulbs. I've found a couple with dead/half-dead balasts. The
main parts of the space are much more evenly lit.
Right now I think you're right, we should fix up the shop/classroom lights
with local switches. I'm pretty much available most days/evenings to work
on things for the next few weeks.
I've now counted 44 working 8' bulbs. Most of them are 60W with a couple
75W bulbs. I don't know if mixing 75/60 is bad for the balasts we have.
Next up I'm going to try and get TED-5000 units hooked up to measure what
we're using where.
