LED lighting retrofit for office / medical buildings
I am looking to see if anyone here has experience doing lighting retrofits in commercial buildings. I work for a owner operator of a few office and/or medical buildings in a city offering rebates for up to 50% of the cost of the project. Obviously this is beneficial to not only the energy/cost savings, but it adds value to the building that the local utility will help pay for. So, does anyone have experience with LED lighting technology? What is the current state of the technology? What's the most cost/energy effective right now?

They make replacement bulbs that you can screw into your current fixtures and have the building staff do all the installation.  PM if you want some more info.\n\nThe cost is paid off in less then 2 years with all the savings and the bulbs have a 7 year life.  It goes straight to the bottom line and increases NOI, thus sale value.", "replies": [], "depth": 1}, {"id": "d8smbw1", "text": "I've converted a number of buildings over to LED. My advice is to start with all of your high wattage fixtures and work your way down. Basically any existing bulbs/fixtures that are 100w+ will have your best ROI ( think parking lot/structure lights, exterior lights, high bay fixtures, lobby lighting, etc.) Be careful when choosing your products as there is a lot of junk on the market. Stay away from cheap \"retrofit\" products. Make sure you have a full understanding of any product warranties as well as any potential utility rebates or incentives, and take advantage of all of them!", "replies": [], "depth": 1}]
