okay so i have 2X 4 lamp F96t12 Fixtures in my garage with cheep Sylvania 60 watt 60 cri lamps and they have a gross yellow to them, in my grandpas garadge i put up lights for him awile ago, there is 3 2 lamp F96t12 fixtures with vintage sylvania 75 watt 60 cri lamps in they have a nice white light to them so i asked my grandpa if i could trade lamps with him he seid yes so i put up the vintage tubes in one of my 4 lampers and they have the same gross yellow to them whats going on they have the same brightness as my 60 watt ones too and i hate that yellow but before they had a nice pure white?? whats going on someone please explain!

note: i my fixtures are in desperate need of a repaint and they are not white anymore due to UV

the left fixture has 75 watt lamps and the other had 60 watt lamps

i did a lux reading and the 75 watt ones are brigher at around 20,000 lux and the 60 watt ones at 14,000 lux at my waist height

also my ballasts are magnetic and my grandpas are electronic
