Hello, I looking to transition our CFL recessed lighting to LEDu2019s. Background: - We have Phillips PLC 26W 835 4 P CFLu2019s o http://www.prolighting.com/cfpl2626w35q.html - The ballast is a PSM226CQMVDW o http://www.robertsonww.com/ - # of CFL recessed lights: 1,000 - Commercial 4 story building. Questions: 1. Do you have any recommendations on any comparable LED lights? 2. Would those LED lights need a ballast? 3. Would the existing fixtures work with LED light? 4. Would there need to be any modifications to any of the wiring? Thanks! Show More
