If the lights are vented in line with air passing from outside the room, thru the lights, and exiting the room, the scrubber would not be a consideration at all (assuming the flex hose is uncompromised) But if you're drawing air from the room, thru the lights, then out of the room, you'd need the scrubber connected inline before the lights.

I hope the question you asked and the question I answered are the same question.....

Yeah,,cause pushing air thru the scrubber is not a good idea.

Yes, you can use your existing scrubber inline with your lights using cooltubes. I am cheap so I attached a small fan to the light hood blowing directly on the bulb. My room is 3' d 6' w 7.5' h. Temps are, inside room, 77 degrees f, temp at top of plant 77-80 depending on fan speed (8'' booster fan) not the best but has to do for now. Basement temp 68-70, intake is 13x6 exaust is 6''. Light ( 430 watt ) is 8'' away from plants ( scrog ) for over 5000 foot candles on my meter, 2000 is minimum. There is a larger 15'' fan blowing the same direction as the small fan.

What does a fan blowing on an exposed bulb do? I guess it would cool the bulb, but won't affect the room temps at all.

The idea is to get the heat away from the top of the plant. . Get the heat away from the plant and your exhaust will do the rest.

Are your lights sealed? if so then pull air from outside the room thru the lights with flex duct connecting the lights to fan.
If the lights are not sealed them a larger cfm fan is needed.

Where are you drawing from? and where are you exhausting to?

I run sealed with CO2. Lights draw from outside(lung room) the tent thru the sealed lights then connects to a wye. The other inlet on the wye is coming from exhausting the interior of the tent. The exhaust from the wye goes to a carbon filter. I have to fans which connect just prior to the wye.

@Cubby .....I am having a problem posting my drawing. But here it is in a nut shell.

The ventilation for the lights runs from outside the tent, thru the lights, back outside the tent to a fan.

The ventilation for the tent(air and heat exchange) comes out the top, to another fan.
The intake and exhaust for this run both have dampers on the end. These allow the CO2 to be kept in the tent and not be exhausted.

From these 2 fans the exhausted air connects to a wye that then connects to a carbon filter.

The carbon filter is at the end of the line and is completely outside of the room the tent is in.
