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?
