PAR meters and Spectral Analyzers don't measure the quality of the parts and build quality. I've never said a white LED can't be improved by tweaking the spectrum by adding mono's, I've been doing it for years. what is at question is ratios and benefits verses the complexity and cost.
You can not continue to play the cheap diode game any longer. That is a red herring. Chinese production is across the board improved or your ;lights would be crappy, as well. Al from the same city and maybe even the same factory. you do not even know. PAR and Spectrum Analysis places all players on equal playing field. Quality of parts will show during testing,a s well as quality of testing. Most every company I posted has a QC program, UL listed, as well as other requirements.
Nothing wrong with what you are doing, but that does not make them wrong either with what they are doing. The question still is while claims are made, how many have submitted their lights for PAR and Spectrum Analysis testing, as well as UL and other QC issues? Probably not, and that is OK too. That is what DIY is. DIY is NOT saying the experts get it wrong and they cheat and use cheap parts. They are experts because they have made the commitment to testing and inspection, the core requirements for any production company for public consumption.
learning from the experts is how DIY improves not becomes cheap parts and cheap labor. you can not tweak parts and labor with PAR meters and spectral analysis together.
You may have NOT said COB's can't be improved, but I would suggest you read responses from others on that same subject matter.
I am not here to fight, but I am not taking the bad treatment any longer. ALL opinions are equal until proven otherwise. I live by that people here should try that same.
What I am doing is fine for me. Because you do not agree with what I am doping, does not make it right or wrong, it just means you do not understand what I am doing, and that is neither right or wrong either. it is what it is. But I have not attacked anyone over anything. I am just resolute in my views and understanding of lighting and it's impact on plant growth and development until facts prove otherwise. So far facts have been helping me move forward. I share facts but that hurts some folks. sorry.
