Rives, I wouldn't tell you how to wire a house, this is my profession. It's like me wiring up light controller just like one of the shittier commercial brands I've heard you talk about, and then when you suggest changes that you know will make it better... I tell you that your arguments are arbitrary and that you should stop putting down my panel and others like it available for sale. Doesn't make much sense does it?
Not only did I teach you how to properly mount the LEDs on MCPCBs to build your DIY array, I've looked at hundreds of commercial LED arrays over the years and professionally evaluated them for a consultation fee. Sometimes I evaluate them again after changes are made before they go to market. I do happen to know a little bit about what I'm talking about here.
If you plug a new lumigrow in, measure light output, and check it again in 5 years, it'll be less than 50% output. Couple cheap computer fans are less money than enough aluminum to properly heatsink the array.
If you aren't using some CAD software to look at what's actually happening with light dispersion you might have trouble visualizing what I'm trying to explain.
The PLLs you used Rives have an unideal dispersion, they throw light in 360 degrees, trying to mimic this with LEDs is counter productive. The array should be spread out, with light going straight downward, there is no argument to this... Though I'm sure there will be plenty of people to find something to disagree with just for the point of disagreeing with me.
Not using secondary optics is either profit maximizing, for foolish design. the "120 degree angle" is not an even blanket of light. the centre is at 100% while at 60 degrees away from centre you'll have about 10% the output. Secondary optics with spread out LEDs are needed to create a properly even blanket of light.
