Exactly how does the hot air flow around the pendants?

I'm not really sure about the best way to go about cooling in the canopy. I've seen other's threads and the venting out....but can someone explain the flow of the air please?

This is what I thought happens:

If you place air fans that vent out centered above your pendant, then the air surrounding each side equally gets lifted up and out. This is supposed to provide the best cooling placement.


Is this correct? So if I got dual fans for above each halide pendant, it should pull up air equally?

Also, I want to blow across the top of the tank so the heat does not warp the eurobracing (acrylic). Which way does it need to blow to get it up and out without bouncing the air back into the canopy and recirculating it?

If I have a fan on the side of the canopy blowing in, won't I have light streaming out of the hole? I would like to avoid the bleeding of light.


These are the fans I was thinking of getting......any experience with these?

This is going in a 6 foot long tank x 30" wide. No options to use ducts to vent.

Thanks very much in advance for your help!
