Good morning guys,well it has come time for me to start replacing my 20 plus yr old fluorescent light fixtures.Having 12 of them and over time 4 of them no longer works which I did check bulbs and the sockets.I went down to my local HD to purchase new ballast but dang,I can just about buy a new fluorescent fixture for just alittle more money,but which one?What bulb buts out the most for someone who has a hard time seeing in daylight? I have 8' ceiling height so they will be mounted to the ceiling and not hanging down.Is there any online source that's cheaper than local big box stores?Looking for ideals-----kroll
