I did the direct drop in replacement, still in process. I had T8 in banks of three per ballast/light, but I am replacing 19 banks with only two LED replacements each on the 5000k 'blue' kind.
I believe I will go from something like 1600W to around 650W for the entire thing. The boxes of them I'm buying off Amazon are about $60 shipped for 10, so that is 4 boxes at $240 total to replace them. Not sure on ROI, might be a couple years. -Sterling -----Original Message----- From: Af [mailto:af-boun...@afmug.com] On Behalf Of Christopher Tyler Sent: Wednesday, November 16, 2016 9:50 AM To: af@afmug.com Subject: Re: [AFMUG] OT Office Lighting Change to LED They make both kinds of LED lights. Direct drop in replacements and those which run directly off of AC power which have to have the ballast removed. -- Christopher Tyler MTCRE/MTCNA/MTCTCE/MTCWE Total Highspeed Internet Services 417.851.1107 ----- Original Message ----- From: "Bill Prince" <part15...@gmail.com> To: af@afmug.com Sent: Tuesday, November 15, 2016 6:31:56 PM Subject: Re: [AFMUG] OT Office Lighting Change to LED 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 bp <part15sbs{at}gmail{dot}com> On 10/11/2016 10:30 AM, Sterling Jacobson wrote: 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?
