A retrofit is when you go back into a building that already exists and modify what was in place and put something new there. So, the clearest example of a retrofit would be going into a warehouse that has fluorescent tubes, utilizing the wiring that’s already in place, and retrofitting the fixtures with Driver and LED tubes. Going back and restoring and old building is another way to describe a retrofit.
