I will also relate what we did in our kitchen.
Our kitchen had two recessed fluorescent lights that consumed about 160
watts total. We replaced those with 9 recessed LED lights that consume
60 watts total. So we save about 100 watts if we run them at 100% power;
which we rarely do.
The LED lights are on a dimmer, and we typically run them at 10-50% of
full power. using this as a factor, I would say we're actually using
something closer to 30 watts on a continuous basis. So we are actually
using ~~ 130 watts less power.
We run these lights maybe 5-8 hours per day, so it add up.
We are also in the "triple penalty box" with regard to our power
consumption, so the incremental power costs us close to 30 cents a
kilowatt hour.
In the final analysis, the lights save us "maybe" about $100 per year.
Not bad.
However, the lights and the "cans" cost about $500; just for the lights.
On that basis, maybe about a 5 year ROI.
That does not count the cost of re-designing the ceiling, construction,
texturing, and painting. Probably a couple thousand dollars.
So not a good investment from that stand point.
However... The lights are at least 2-3 times brighter than the
fluorescent lights plus the light is more human friendly.
We would definitely do it again.

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?
