The other thing that needs to be understood is that it should be done now while there are no homes in the immediate area.  Once homes spring up, you cannot install lighting.  But, if you build the stadium first, then it's grandfathered so if any homes DO spring up near the stadium later on, home buyers cannot complain (though they will probably still do so).  This is why some school fields with no lighting such as Punahou and Iolani cannot install field lights now because homes are now located nearby.  Not sure how Farrington got around that, but maybe it's because the field is far away enough from any homes.
