Yea bro, I've got a 250cfm inline fan I bought for a 400w HID, and the light laughs at it, almost no help at all... I'm going to hook one of these up to it as well and see what difference the both of them make.
You need at least one of these to do that properly.... I'd do it with no less than this knowing what I now know.

Here is some useful information I picked up from a grow book by Gorge Cervantes
" Vent fans are usually attached to ducting to direct air out of the grow room. Flexible ducting is easier to use than rigid ducting. Keep the ducting straight and short. Long runs of ducting cause less air to be expelled and at a slower rate. When ducting turns more than 30 degrees, air movement declines and less air exits the other end. Ducting at no angle moves the most air. Ducting at a 90 degree angle moves the least air."
I saw in your first picture that the exit exhaust Ducting is at a straight 90 degree turn. If I had to guess your fan is not moving any air at all, or very little so your 1000w HPS bulb is getting some serious heat buildup. I hops this helped.
Peace and positive energy to you.

I've got a stanley blower and am about to pick up another, there awsome and only $50 and can easily be modded for 6'' ducting. you can pick them up at home depot

.........Do you vent cold air in??If not then your room/area will start to warm up.....Without an a/c or cool air intake...your room/area will continue to warm up....one solution is to set your ventilation like this......outside--------->>>ducting-------------->>>cool tube-------->>>ducting--------fan--------->>outside-------->>>>>> then with another fan pump cool air in or get an a/c........if another fan is not an option then leave the way you have it....but try to keep your grow area as sealed as possible and put an intake duct.....like that the fan is sucking the air out creating a vacuum forcing air in from the intake...make sure the intake is hooked up where it has access to cold cool air.......those 1000 watt lights are not cheap to keep cool.....I don't know what region your in but if you have hot summers like I do you might need an a/c...

A cool can NOT stop radiant heat. Radiant heat the the heat produced by the IR light. That light travels through the cool tube and into the grow area.
Just think of the Sun. Between it and Earth, there is no air, but boy does this planet heat up from the Sun.
You need to cool the room too.

You are WRONG!!! The reason radiant heat is transfered from the sun to earth is because there is no AIR and nothing to impede its travel. If you push enough air the radiant heat has no option but to heat the air that is passing by. Radiant heat does not pass freely through gases solids or liquids. but can through space.

Yes but no matter how cold the air is the radiant heat source will still stay hot and emit heat......it says so on the wikipedia link you provided......

Yea I had/have that same 8" booster fan that is rated at 500cfm, BUT prior to this fan I had a nice 250cfm fan and to be honest when I put my hand up to the ducting the 250cfm fan seemed to pull more air than the 500cfm one... It does not make sense at all but idk, I think im going to put the old fan back in and return the 8' fan to home depot.
I am having some serious heat issues as well. Ambient temp are in the mid 80's and my grow box is in the upper 90's. The plants seem to be doing fine so we will see what happens.
This is my first indoor grow I have 15+years growing outside so I think what I am going to do is just grow indoors when its cooler out maybe sept-april so it will not be a killer to cool the area.
