Except that's just repeating what I said. Nobody does that because 250Ws are terrible. LEDs don't have that problem. Maybe you skimmed or something.

Of course it was implied, but you can't be too careful with guys like(churchhaze) this just waiting to jump down your throat.
I gotta be careful or I'm a sock account or a troll...
Diffused overlapping light imo is better.

Well, I was thinking of light loss due to diffusion. Diffuse light definitely penetrates a canopy better, that's undisputed as far as I know. But diffusion also steals light, so it's a tradeoff. In a small tent I doubt it matters, and I have no idea otherwise. Maybe running a cob per sq ft is enough, maybe it only applies to greenhouses and the sun.
And yeah, PPFD is PPFD, which is kind of the crux of this whole thread. A hung HPS uses a reflector to spread that light as evenly as possible because hotspots are not good.
What you have illustrated here is that 4 250w hps does not produce the same amount of light as a 1000w light. Lower efficiency. That's an issue specific to the 250w hps technology. In this case I agree with you, but it because the 250watt hps sucks.
yes. and it is also additive, which means for overlapping light sources the light intensity increases proportionally.

This diagram is a perfect example of what I've been trying to say.
600's spread out is the least you'd go in a grow room. They have the intensity & spread to flower big, hard nugz!
400's spread out is the least you'd go in a smal tent relying on the reflection to equal you back out to 600's.
Thank you for proving my point with this pretty picture.
You are arguing the same thing but with much lower powered fixtures. In case you forgot what you were arguing about.
It's hard to argue the truth, I'm sure.
So why keep trying & putting people down in the process.
Again, an LED fixture should be a 600 watt HPS equivalent & spread out on a grow room to achieve HPS size & density nugs! It's not even something to argue about! It's a fact!!!!

Sure. A 600W equivalent like a 250W SE-250. Keep thinking about it, maybe you'll get there.

"How does increasing levels of low-driven COBs increase penetration or density?"
Good question.

It increases total light. I mean, are you honestly struggling with this?

Only
Adding all 4 together will not actually give you that # in density @ any one point.
More like an even 20-30,000 lumens across the board. Or a little more then whatever a 250 bulb puts out alone!
Meaning there's never enough intensity or density to flower marijuana plant to have big , hard nugs. Just Flarf!!!
Only thing I disagree with here is that 4, 250's will not achieve 112,000 lumens @ any given point of measurement.

I can't believe you're struggling with this.
I actually grow pot in a room depending on the lights not the walls to flower my pot & I want to flower my plants @ least 2-3' down past the top of the canopy not just the top 6".
I thought you'd want it big, long, n hard.
But maybe you prefer it 4-6" n soft.
But does not increase density enough.

This statement doesn't make any sense. Lumens isn't a measure of intensity that can be measured at a given point. Lumens is a total that can only be found from looking at ALL points.
I know you really do think you're the only one here who gets it, but you keep showing that you don't even understand the terms you're using.

N you seek any technicality possible to avoid sounding as wrong as you are.

I'm afraid it's a bit more than a technicality. 4x28055.5lm = 112222lm
You have stupid thoughts in your head.

It will not achieve 112,000 lumens from any one point.
Only disperse x4 low output sources of let's say 25,000 lumens each as a guesstimate.
W/ the overlap you may achieve 35,000 if your lucky. But I'm using these #'s as an example rather then looking up the Lumenous value of a 250 bulb & doing the math equations. Someone else can do all that.
But that doesn't mean my point is not valid.
Dig for technicalities all you want.
I grow 1 pound per 600 watt HPS bulb consistently x12 plants every harvest.

nobody said that.
112,000 lumens is the approximate total amount of light produced by 4 of those lights, where as 140,000 lumens is an approximate total amount of light produced by 1K. in this case because of the technology it will take about 5 250hps to produce the same amount of light as a 1000hps.
The total amount of light produced by any lamp is NOT the same as the instantaneous reading at any point on the canopy.
This is like the difference between "PPF" of a lamp versus the "PPFD" at any point on the canopy.
Learn to understand what people have been trying to say, ignorance and refusal to learn makes you the one trolling this thread.
