For office maybe, I wouldn’t put 5000K bulbs in my house.

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.

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. *From:*Af [mailto:[email protected] <mailto:[email protected]> ] *On Behalf Of *Josh Reynolds *Sent:* Tuesday, October 11, 2016 11:39 AM *To:* [email protected] <mailto:[email protected]> *Subject:* Re: [AFMUG] OT Office Lighting Change to LED 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? -- If you only see yourself as part of the team but you don't see your team as part of yourself you have already failed as part of the team.
