Yea, I have herd people talk shit about cool tubes too. Its the small reflector thats put inside the glass tube that people don't like. You can just remove it and use other reflective material if you like. I got the real deal and I made my own for my cabinet. But yea, any air cooled reflector will be good.
You have a 10x10 area and want some ideas? Check out GTOs journal he sectioned off part of his garage and built a room thats pretty cool.

I do not consider his room the most efficient way but it works.
He is in Montana cold winters and hot summers too.
But he is only growing his legal limit.
I have read hundreds of journals, I learn something most every time.
Air movement. Whats important to remember is the more plant material you have the more CO2 they are going to use. Fresh air has 300ppm of CO2 in it naturally. CO2 is heaver then air so it is low to the ground. What you want to do is get air from outside in one side of your room at about knee height. Have a couple small oscillating fans blow the air up under the leaf where the stomna will take it in and make oxygen. Then on the other side of the room at the ceiling you go out. This is for the plants environment.
You should vent your lights almost the same way. air from outside through a vented hood and back out but both can be at ceiling height.
This way you can control the environment. Control the Temperature, humidity and add supplemental CO2. This can be done manually or with a controller. Its nice to have it automated but not necessary. You can get it close.
If the same fan cools your lights and your room you will run it quite often and will never be able to control the environment. you will have almost zero humidity and a constant 300ppm CO2
So, when you ask what size fan do I need it depends on what you are going to do with it. 4in in line fans are about 200cfm. Fans are more effective pushing air then pulling it. So the fan on the lights would be pushing it past them and the fan exhausting the room would be where it actually goes out of the room. You don't necessarily need a intake fan, just fresh air at knee level.
Squirrel cage fans are cheaper and move more air then in line fans but they don't move the air very far.
At minimum I would get a 200cfm in line and use 4 in ducting to cool the lights, right at the exhaust outside I would add a duct booster. Then about the same (200CFM) for the environment but squirrel cage type for exhaust if it is just going through a wall.
I made plans for a room I plan to build if I ever get the space. Light hung vertically and plants in a stadium grow. two flower rooms on a flip flop switch so the ballast never turns off. One room on 12hrs then the other. No power surge every 12 hrs. Much more efficient.
I will look and see if I can find it.
