You're making me nervous man haha. I'm planning on buying a 4-bulb fixture for the 40b that I'm planning on building
Don't be! 1st of all, what fixture?
2nd of all, my 75 is quite a bit deeper than your 40B! So you're fine.
Now are you planning on full SPS dominated or? If so, maybe you should do a 6 bulb!
