Are LED's practical for a grow room? (24 ft x 12 ft)

Depends on your budget and your willingness/ability to DIY. DE HPS will certainly be the more economical option. DIY LED will be a close second.
You also need to consider how long you plan to grow in this space. I wouldn't invest in LED if you only plan to operate there for a year or two.

Go 1000w DE HPS. You won't be disappointed.

If he's looking for cheaper electricity bills and cooler room temperatures, why wouldn't COBS be for him, despite the large operating size?...
My only fizz about investing into COB technology is a.) every year the products for Cree and BridgeLUX become more efficient, and b.) there aren't really any solid COB-infused lights out there yet, at least not for a 24' x 12' grow space..

Fans will help move air from one location to another but will surely add heat to the room and it adds up quick if there is no outside source of cooler temperature. In other words, if you have fans in a closed room, such as the 24' x 12', without exhausts, the heat will just bounce around the grow room, with the fan's power consumption turning into heat. further rising temperatures.Thanks for the quick responses guys
Are a lot of fans the recommended method for intense cooling of the room? (summer months, no air conditioning)

Some interesting results.

Oh I know, still really enjoyed how they put the video/comparison together. Even still the final results favor those silly spectrums over everything.
A DIY on this scale would be amazing.

If he's only going to be there for 2 years he would invest more into lighting than he would save on electricity. There would be no savings on buying new bulbs.
Even if he only lit 144square feet with 2530's he's looking at almost $2k for just emitters at bulk rate. Not counting heatsinks, fans, power supply, assembly time, etc.
If he plans on staying there permanently then cobs would be worthwhile investment. There is a lot more to consider on a large scale.
Either way, you're looking at several kWh of power, that's going to require an ac, led or not.

Osram top bins hitting over 50% efficiency(even reds) outdated????Purpleeeeeee!
By the way, BML is outdated.
It may not be the ultimate spectrum(or it may be)...but it's more efficient than just about any other light out...even every vero based light I have ever seen or heard of.
Passive with insufficient heat sinks is the real downfall. If it was actively cooled, there would be a lot of talk and use of bml.
Step out of your bubble
EDIT:
There price is a huge issue too. When apache is the affordable option, that's an issue.

Go mostly DE HPS 1000W, and a small area with DIY cxb to try it out.

You automatically assume I'm picking at efficiency and the quality of Osram's products...
Please kind sir, step out of your bubble.
He never said how long he was going to be using the lights, so why assume something so hard headily? Again, he never said he was looking to save money but wanted to fight against temperature. And air conditioning ain't cheap nor efficient.

Then elaborate on why it's outdated.
And as for saving money...he specifically said he wanted to.
I know about leds as a whole(95%+ of them and what they can and can't do) ...you know some about cobs, veros sepcifically. My bubble encompasses yours. And my bubble also merges with hps and induction. As well as a few grow methods. Dare I call my bubble a world or planet...with many different lands/counties of expertise. Not just cobland and its' inhabitants.

Actually a 24k btu mini split would cost about the same as emitters for a diy build. And he would only need 6 de hps to cover the same canopy.
He asked if they are practical for a large space. To be honest at this moment in time they are not that practical on a large scale like that.
Im all for a large scale cob build. But 3000w of led is going to cost a pretty penny and is still going to generate over 9000btu of thermal energy that is going to need to bedfelt with.
