Do light fixtures need to have power allocated based on max permissible lamp watts?

[Electric-Light]

if a ballast is rated 0.39A with 48" T8 25W energy saver lamp and 0.49A with F32T8/32W full wattage lamps, but you intend on commencing the system with 25W lamps, do each fixture need to be allocated 0.49A of current?
