osram SSL for last few years,
OSRAM has new SSL's out now. They are looking good.
My theory on monos is has to do with horrible thermal curve on red. It is very difficult to run them at 25°C. I doubt many run them below 100°C.
Now CoBs, are where the research and development budget goes. Deep Blue LED technology.
Where red loses 50% flux due to temperature, deep blue and white lose 10% max.
My focus has been on thermal management.
the mccree curve is what drove people to use blurples
I don't think McCree really supports BR that well. I don't know where they get the Photosynthesis Rate Curve, not McCree.
I took all the McCree numbers and graphed them. This is what I got:
Red and Blue were likley pushed because they are the most efficient LEDs. Green is the least efficient. Who uses green besides traffic lights. Who needs efficient green when our eyes add 10x brightness?
There is more to it than BR. Research using the scientific method, takes way too long. Eventually they will find that elusive wavelength(s) between blue and red. Until then, white will have to do.
It may be yellow amber. Amber the worst thermal curve. Can easily lose 80-90% at 100°C. Although there is a Luxeon phosphor amber (i.e. very warm white). I would never use Luxeon Sun Plus purples. I do like the Color C Line which is the same technology as Sun Plus.
My approach is Red White and Blue with adjustable LED drivers.
What I see the CoB crowd needs is an improved way to power the CoBs. A single 36-48V CC supply with a load balancer that will accurately divide the current to each CoB as desired. Example, nine 1 Amp CoBs, a 10 Amp supply and a circuit board with nine 1 Amp outputs. That would be a cheap and easy product to make.
The chips on this board can handle 1.5 Amp each.
The 90 Cri Produced Exactly 179.7 grams And The 80 Cri Produced 213.2 For A Difference Of 33.9 Grams.
