Default air cooled tubes Vs air cooled hoods

Well I thought i would put the question out there for a few comments on both and which is better as far as total light output/Lumens

Both are ducted with cool air running
which works better

air cooled hoods 6" or air cooled tubes. looking for a comment from someone who has used both.

Room is not an issue in this one. Just want best light coverage

A hood proly has better coverage, but really they are pretty much gonna do the same job.

hoods will give you wider spread of light. Cool tubes tend to go more straight down for better light penetration on the canopy. Just a matter of personal choice. Myself I prefurr the cool tubes.

It is the room that is the issue here. If you need a large foot print cool tubes suck.

What he said. Although cool tubes take care of the heat a little easier IMO.

Default cool tubes vs hoods

thank you for the replies:

As I suspected the tubes are good for limited space applications and want more lights. I will stick with the current layout of hoods .

Adding more and just wanted another persons opinion.

No one even mentioned the effects of air flow. The hood will offer less resistance on your exhuast, unless you have a cool tube that's 6" in diameter or something. Putting a cool tube on your system can be like putting a kink in a hose. You decrease the diameter and that dampens the air flow. The hood is more open and the light it self doesn't really even add any resistance like it does in a cool tube. Cool tubes are really just a poor mans air cooled hood, the only reason companies even sell them is because they saw an opportunity to make something cheap and sell it for much more money. They aren't scientifically any better, they are actually worse because like I've said the diameter on them is very big so that decreases your total amount of volume and you have your light inside the tube that decreases the amount of space for the volume of air to move through causing the system to pressurize.

Air cooled hood all the way, better coverage, better air flow, and you can get better canopy penetration because with a good exhaust you can get a air cooled hood even closer than a cool tube and if you get the right kind of hood you can adjust the position of the light to widen or narrow the light coverage giving you better coverage or penetration depending on what you see fit.

In short, cool tubes = junk when compared to an air cooled hood.

Thats great info, I thought cool tubes would be better. Glad I have an air cooled hood and didn't go buy a cool tube.
