I imagine the file he sends back to her would look like this.
They just need to send him one of their replacement PCB's with diodes not a 450$ fixture. Highest output per watt diodes and and best thermal heat transfer with this plastic edison housings, lol! Never heard such nonsense before.. We would all use them if they would be better, no?
Osram has worked with the Nasa from the beginning and Sanlight was the 1st partner developing LED's for hobby growers. The spectrums HGL use looks pretty similar to the Sanlight spectrum because they just have copied what Osram has figured out in decades and claim it their own developement, lol!
Sanlights have 2,7μMol/j system efficiency, I wonder when HGL has 2,0 without lens. With its probably even less...
The whole test grow is useless cause I can also create 1000μMol/s with 4 Mars lights. For a fair test he needs to compare them at the same wattage. Osram has proven many times that a combo from blue, green and red is most efficient as growlight BUT 3k reach almost the same efficiency and even Osram use coolwhite/CRI70, warmwhite/CRI90 + their best red and deepreds to create the white spectrum of the Sanlights with just a little pinkish tint.
