Cool Tube with a Wing or Magnum XXXL 8"

Was wondering what you guys would do???

8" Ducting and 8-10" Fan will be used, so 8" Reflectors are a must.

More air+Faster Speed Fan = Cooler Lighting

My top picks

Magnum XXXL 8" Air cooled reflector

8" Cooltube

Radiant 8"



I will have 4 600 watters on light movers as close to the plants as i can get them and i am leaning towards getting the XXXL because i think it would cover a larger area.

xxxl.....more area, and they run cooler than the tubes in my experience.

4-1kw's on 2-6" 460 cfm's , plenty cool enough. be careful how close you put them to the plants. You still have to get your distance. I like the size of 6" duct is small spaces. how large of a space you trying to cover? soil or hydro?

I will be using 600's. I like the economical lumen/watt ratio. plus i may have multiple rooms in the same home with the 600's, cant do it with the same amount of 1000's without throwing up flags... A/C costs a lot.
Also planning on getting diffusers, I dont hear alot of people on here saying they use them... may start a thread about them.
8" is for an easier flow for the fans, i can run a 10" fan to a 10-8-8 Y Duct to two lights then out to another room.(all growing areas will be sealed the exausts will also have backdraft dampers on them.
the Growing area of each room will depend on the way i grow.
I will be going aeroponic for sure, just not sure if im going aero/nft or aero/dwc... thats another topic tho.

The rooms will be atleast 10x12 ideally 10x14-15

sounds like a man with a plan. is this all still in the planning stages? i would love to be kept in the loop as far as progress goes.

I did not make my post clear. I use the 1kw's on 6" with no heat what so ever, 1 on 2

so what did you end up buying ?

I need to get temps down inside my tent, and I was thinking of getting a cool tube and attaching a wing. What was your experience with the cool tube versus another reflector? Why do you think the tube ran hotter, because the bulb is enclosed in such a small space?

Peace and Thanks

I would say they aren't comparable. magnum xxxl is a huge reflector, cooltube is a small and the most efficient air cooled design available...

depends on your setup and what you are looking for, but a cooltube is probably better since it is easy to move and set up and cool.


having worked with both types I use a 6" cooltube for my 1,000w HPS and w/ a quality booster fan pulling air I don't even need a real centrifugal blower to vent my hps temps out of the house.

wtf...
^_^

I use cool tubes with wing reflectors in my tents great for all sizes I prefer 600 watt lights mysel. I can hold the cool tube in my hand and use just simple inline fans from home depot one blowing air in 1 on other end sucking out. Tent stays around 72-75 i turn a fan or 2 off if I want warmer for co2. here s a looks at them in a tent and what they produce...

Oh and forgot it also helps you get those nice extras from good grows, like hash. i am all for cool tubes. i bought mine for $65 each and wish i bought 10 more

What is your ambient temp FF?

The temp with the simple duct fans running in the tent is about 76 outside the tens I run the lights at dark the temps are around 75-80 when I run the co2 I turn the fans off on the tubes and can get the tent up to about 80 ish.

thanks for the input Filthy, i am looking to now do 1kw in a 4x4 tent with a batwing and a 6"cooltube/Icebox setup. But it will be after the summer is over.

I spent a lot of time researching the whole temp vs. lumen output/spread topic, and found that it depends quite a bit on the strain you have and the light it requires. If you want the most intense spread of light in a 4 X 4 area, the Super Sun 2 reflector can't be beat. If your choice is to spread the light out more, go with one of the other Hydrofarm Radiant or Daystar reflectors or one of the magnum style reflectors you guys are referring to. Cooltubes offer only one advantage, and that is temperature reduction. Those "batwing" style reflectors are HORRIBLE in comparison to the traditional reflectors when it comes to putting the lumens down, and in a good amount/spread.

thank you Mcgician for the input. magnum 8" with an 8" icebox would be ideal. but 8" iceboxes aren't in production yet... or aren't readily available. and strains vary from 9-11 week flower times. mostly sativa dominant. my only indica dom strain is blueberry.

I wouldn't have recommended a reflector with an 8" hole anyway. I've tried searching for the thread I got alot of the info I've collected, but the search function on here kinda sucks. I can't seem to find it anywhere. It was referred to me by bostongeorge54. Too much light escapes out the hole when you have to deal with an 8" duct. The Daystar or Radiant 6" reflectors do an outstanding job and so do the other Sun System 6" reflectors like the Cool Sun. I went with the Super Sun 2 reflector myself, because my lights are moving anyway. Regardless of what results you may be seeing from others, there's no way around the physics of light refraction. Like I said, the ONLY advantage to cooltubes is heat dissapation. The "batwing" style reflector growers and vertical reflectorless growers will tell you different, but get out a light meter and do the measurements yourself. The numbers don't lie. Best of luck in whatever you decide.

with cool tubes the batwing is fine as there is a reflector inside the tubes also its a half moon pebble finish then the wing lets you bend it to direct the outside ligthing or have the reflector lside to cast light at angles. In the cool tube you also have both ends with ducting so light doesnt go out from there. Heres a few quick pictures at an old setup I had from way back when i still use it for littl side grows. its a homemade 4x4 tent with a 3x3 table with 1 1000 watt hortilux hps light in a half barel open ended reflectors. just fans in the tent moving air one sucking fresh air in. I have sogged in this but find about 6-10 plants is plenty and have gone with the 7 plants right now so 7 sweet purples running fox farm nutes 4 floods aday this is week 1 finished flower temps with lights on around 70 with flap open and if I run co2 I close the flap always and have it about 80-82 in there up high at at plat tops fans blow constantly so temps at 78

super sun 2 if you have your lights close enough together (thats what i got).
if you have your lights spaced far apart (or just one light in a large space) than get a big reflector like the magnum xxxxL.
