I think you have to careful be saying things like NEVER or NOT EVER. You may be right that the CXB 3590 won't perform to those levels, but COB's are a still evolving technology where HPS is pretty well developed at this point. I'm not sure what your background in electronics or microprocessors are, but I believe we will see similar gains as what were found in that industry. The limiting factors in these COB's are diode size, material science, and tooling to produce new designs efficiently. All of these things will improve in the years to come and I have no doubt someone will eventually develop a purpose built COB especially for horticultural applications.....if it hasn't been done already.
As far as penetration goes, I tend to agree with you but am not totally convinced that these COB's won't be able to stand the test. Especially when placed close enough together, where wave theory tells us they will amplify each other. The other thing that I think you may be overlooking is the size of the element. A 1000 watt bulb element is several inches long and projects light in 360 degrees. So when doing a point source calculation you have to consider the density of photons at their origin. Like spokes on a tire, they get further and further away from each other the further you go from the center. The light emitting part of a COB is something like 32 x 32mm and only projects light in 110 degree pattern. That's pretty damn small. So the light being emitted from that small area should be very dense considering the high lumen efficacy. This should translate to relatively good penetration DIRECTLY UNDER the COB. This is where getting them close enough together becomes key.
Anyhow, we will see. I already have all the HPS technology I need. If in fact you are right and there isn't a significant advantage to running these then I may go back to HPS and use the COB's in Veg where I am sure they will perform at least as well as a T5. I will continue forward though in the interest of embracing new technology and doing my part, from a consumer standpoint, to further develop it. Take a looke at what @sixstring is doing. The way he is set up I think he is more likely to produce "Trees" or at least big ass bushes on his ladies, like 80's porn.
Maybe like someone else said, I should just run 20 of these fuckers in a Raptor hood for a 1000watt COB to 1000watt HPS comparison......I have enough to do it but that seems like overkill to me.
Dynamite looking ladies, great looking Nugz! You've obviously honed in your skills under HPS. I wouldn't advocate anyone change if they are growing like you, unless of course they just get bored and want to do something different like me. Thanks for taking the time to check back in!
