Where to start... If you're planning on running 4000 watts of anything, you better do some learnin'.

already have 2000 air cooled hood set up
i use 5 gallon smart pots and successful at it but i want to try bare bulb
i did some research but not really sure about the spacing and lay out

hang them.. right down the middle

Evenly spaced. How else?

Make it so the distance from the wall to each bulb is the same for two closest adjacent walls.

what type of cooling do you have going on?

Because if you are planning a 4000w/6x10 room and dont have AC your screwed

4000W - who´s paying the bill???

You should take one lamp and learn to grow first. Just because you can afford a lot of fancy equipment doesn't mean you will have a successful grow. After you have grown through a couple of life cycles and know how to diagnose disease and pests and know how to use your fertilizer by reading your plants instead of the back of the fertilizer box, you will know enough to set up a large grow like this. Growing plants is not easy and growing inside is even harder and has a big learning curve. Keep it simple at first.
