Purchase an upgrade kit so that you can upgrade your existing luminaire to accommodate LED lamps. Each kit includes D50 LED lamps, instructions, and any necessary components (such as lenses and lamp holders) needed to complete the upgrade onsite. The LED lamp will be directly wired to the AC power line, bypassing the ballast. (Note: The person doing the upgrade needs to have knowledge of wiring and be able to understand a wiring diagram.) GTI’s LED upgrade kits represent the most cost-effective way to transition from fluorescent to high-CRI LED lamp technology.
