I had 5 of the double t8 fixtures installed since the 90s. I recently found on Amazon retrofit kits. The kit removes the ballast, provides a wire for connecting the posts that hold the map. The bulb was a self contained Led and supporting electronics. Daylight and they are not kidding my shop feels like outdoor sunshine on a summer day. There is not noise, radios and wifi work without issues.
