Any time we have a fluorescent ballast die, we just replace

Rip the ballast out and wire it 110 hot. We get 4 foot T8 size
internal
transformer 120v bulbs for like $10 each, shipped. They pull
about 15
watts and put out 30, 35 or 40W "equivalent". I forget exactly
how much.
All I know is, if you have two 35 or 40W bulbs in a fixture now, a
single LED will be damn near the same amount of light (or at least
appear to be). We're remodeling half of the building and all
of those 4
bulb 4' fixtures will get converted to 110 and get two LEDs.
50-60%
reduced power consumption for lighting isn't bad at all. And
all of our
generator backed lighting is LED, so the less load on the
generator the
better.

Looks like I need to check the direct replacement bulbs
from Philips
with my system to see if they are compatible.
If they are, that would be less than $500 shipped to
replace all of
them if I do it myself.
That would probably end up being well under a 1 year ROI
in that case.

Based on the numbers you gave, you'd end up saving around
$14 a year
in power. The installation and equipment could run between
$3500-$4200, roughly.

I haven't researched it much yet, but someone told me
you can't
just use a drop in long bulb replacement.
You have to change out the center piece, forgot what
that's called.
Is that correct?
Is this something I can do myself? Or do I need to
hire a company?
My system has about 24 bays with three bulbs each
drawing about
1500W when they are all working.
Do I save much by going LED on these? What's ROI?
