Any time we have a fluorescent ballast die, we just replace with LEDs.
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.

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.

Anyone ever replaced their standard fluorescence ceiling lights
with LEDs?
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?
