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.
That is a nice setup there. Now I might have to look in to trying to make one or just buy one. Maybe if you get a big enough one you can fit a freezer in and have it turn on at night cooling everything down.
I'm getting new lights for my grow chamber since my project is done, I have more space, and my others lights broke. So shopping bulbs around I found these two types. Which one would be the better bulb to get?
T8 32 watts
CRI 85 6500K
T12 40 watts
CRI 75 6500k
