I'm replacing my bulbs and have two options. They are both GE dalylight. One is T12 40 watts with 3050 lumens. The other is T8 32 watts with 2700 lumens. The package says that the T8 is 30 times brighter then the T12. Both are 65ooK and cri 75.
THEY LIE!!!
(the T8 look a bit brighter because the bulb is narrower, ie less surface area putting out almost the same lumens but not quite = brighter glass. Less lumens is less lumens no matter how you slice it.)
You might want to go with T5 HO which is 52 watt T5s. They are definitely brighter than T12 and put out more lumens. Although, depends on the height where they can still be useless at like 2-3' tall (I am facing that).
