How do I buy a ballast?
By selecting a ballast with an ideal ballast factor, you can optimize the light output of your fluorescent lighting system and maximize your energy savings. To estimate your total system lumens, multiply the rated lumens of your lamp by the ballast factor. For example, 3200 lumens x 0.77 BF = 2464 total system lumens.
