I can take a picture today, although I wouldn't call it a money shot... more like a loose change shot.
Yes, we absolutely coup slam a bunch more LED in there but the point was to SAVE some electricity...
And to the dude debating about led vert l... I see your point, but that isn't what you said initially

It may not be what you read, but that is what I said.
Anyway, I have been giving this some more thought, particularly the reduced distance from the light source part.
Sure, you can reduce the radius of your ring and perhaps add more towers in the same room. But what if you took that to the extreme?
There are many cob chips in the CXB line and they are all very efficient even to low single digit wattages. So why not grow a jungle with micro cobs everywhere?
You would only need as much room as it takes to work and the rest could be greens. Can't think of a more effective way to maximize a room.

There has been a lot of great t5 and t8 led replacement bulbs available lately. Look for at least 130 lumen per watt or better, that is around 40% efficient. The would be a great choice, since the plants could grow right into them (maybe).http://www.ledsmagazine.com/ugc/iif/2016/03/18/green-creative-releases-dlc-qualified-plug-and-play-t5-ho-dir-led-tube.html
If you still want to play with rings, these would work, but I don't think it is as flat panels.http://www.ledsmagazine.com/ugc/iif/2016/03/18/saving-the-environment-one-communitybulb-at-a-time-megaglowledcom.html

The CXB1512 is pushing 200 lm/w at 5w each. The CXB1304 is around 180 lm/w at 3w

But remember, you are already at a dollar per watts for the COBs only. With a bunch of 4 foot t8, your cost could be much lower. At $2 per watt, you could try something like these. http://www.redbirdled.com/resources/RedBird LED Stripit Kit specification_sheet 062015.pdf
I have tested these with a PAR meter against a HO-T5. The T5 was only around 800 on the par meter, while these leds maxed out the meter a 1", and they are dimmable.

Ummmm. What? ... spread 1,000s...yes 1,0000 of leds everywhere? Yeah, that sounds AWESOME!!!!
I don't have a huger bone over LED. If I had to guess, right now the HPS is fucking thumping them.

Yea, was just thinking out loud about how to maximize a given volume.
So the LEDs are having a hard time keeping up, huh? Gee who could have foreseen that.....
"Vert is one area that I think the COBs make less sense."
That is the first sentence of my first post in this thread. You know, the one you didn't really read and responded all butthurt with a math lesson that addressed nothing of what I said.

Is that what your are seeing so far?

Time will tell, but it certainly seems like the hps buds are larger and somehow slightly more developed.
I think I do need to pick another HPS reference plant however. The one we picked has 3 bare bulbs and one bulb with a reflector (because it is the bulb on the edge of the system). Meaning, that plant is getting a little more than 1k worth of light.

I 1 I'll try and upload pictures today. But for a concise summary of the competition:
For sale: 12 cree COB chips, ballasts and heat sinks.
I really wanted it to work, so did my partner, but using almost the same wattage the LED are getting trounced.

sounds like it would make a badass lightbar for a 4x4 or atv/utv.
just like the old coyote/roadrunner cartoons: back to the drawing board!

You can ask me all you want, but I won't have any answers for at least another month. Not every solution works in every situation, every time. Sometimes- shit, most of the time- you learn more from things NOT working as expected!

Is it because these cob lamps won't penetrate a mega plant? So people have to change the way they've been gardening for years for these cobs to not get slaughtered? This is bad news on the commercial front.

Agreed you learn more from failure because you don't want that shit happening again.

You guys that are saying that A. I have a round plant and B. It is a dense canopy are completely and utterly fucking retarded.
Look at the pictures asshat. The plant is trained to a FLAT WIRE FENCE. FLAT. IT'S A FUCKING FLATLAND grow... on its side. Are the lights on the corners? NO. I'm all about constructive criticism, but criticism from shit stains that don't even understand the set up?
The cobs are going to go into a pre veg light system. At least now we know, we bought the best chips and ballasts that they make, and they just didn't deliver.

It's entirely likely that any number of things individually or together could have colored his results. That doesn't mean that A. COB LED has no future or B. that @legallyflying did anything 'wrong', it means that it wasn't a good match for his growing style. That's important, because our growing styles are very much tuned to the equipment we use to do it with.

It means, that LED lick balls is what it means.
My growing style is to hang the lights in front of the plants... I am not certain what else you can do. Maybe I need CFL in the canopy brah..

There's this new system that will light your farts on fire, but at 90% efficiency...
