Which setup should I build?

Hello everybody,
I have a big trouble with my growbox.
So, this is a 4,1x4,1x7,3 (125cmx125cmx225cm) wooden "box". I'm going to buy a 600w HPS, but here comes the problem. I can't decide which light setup should I buy: Go on with a wing or a cooltube? There will be 5 autos( indica hybrid). The biggest problem is the temperature. First, outside the box, in the room. I've checked the temp and it is only 48,2F (9Celsius). Yeah, it is terribly cold, I was surprised af. So I was thinking if the temp is so cold "outside" how warm could it be without a cooltube in the box? But if I don't use a cooltube, I can't put the light so close from the canopy...does this count a lot of lux in this shorter height?
What do you think about this temp and setup? So the main question is: "Wing or cooltube?"
I think the max "outside" temp will be around 59F (15Celsius). [It is a concrete building]
Thanks for everybody who helps

I would recommend using the cooltube, that way you can transfer the heat into the room. It would help raise the temp in the room the box is in, and help prevent condensation on the grow box as well.

Thank you, I think it could work.

A cooltube or a light hood with insulated glass ( that's what I use ) .

Cooltube for sure. Offers most control of environment. If you are playing Mother Nature indoors, you need all of the control you can get.

Thank you all, I've ordered the cooltube set.
