Well the lights got put off for a long time... I finally swapped out 10 of my 4' T8s for Halco LED 4100K bulbs.
I tested a fixture before and after. With the electronic ballast one fixture was pulling .5 amps. After removing the ballast and installing direct wire LEDs the amp draw was cut in half to .25 amps.
The biggest power hogs are the 8' T8s which I haven't decided what to do there. 8' LEDs cost nearly as much as just buying 2 new 4' fixtures. And converting it to 4' bulbs and buying 4' LEDs is in that same area as well.
It's way on the back burner right now but I was able to cut my amp draw a little already. Now if someone built an efficient air compressor...
