A word about fluorescent tubes: NARROWER IS BETTERNever use magnetic ballasts. Electronic ballasts are quieter, more efficient, and eliminate flicker.
Fluorescent Tubes

Electronic vs. Magnetic Ballasts (for tubes)
Electronic ballasts are more efficient than magnetic ballasts … resulting in an overall lamp-ballast system efficacy increase of 15% to 20%.Other advantages of the electronic ballast include reduced weight, quieter operation, and reduced lamp flicker. Electronic ballasts are directly interchangeable with magnetic ballasts. (From LBNL website)You should always use electronic ballasts, especially with motion detectors.
Good Better BEST
