Quantum Board (QB) Vs Chip On Board (COB)

[Aeradix]

I do believe quantum boards will be the dominant design as this is where most of the bigger players are focusing their efforts. That said, the differences are minor for the average home grower and I still happily grow with a blurple Mars-Hydro Mars II 1600.

What a bunch of BS. 

 

"Photopic luminous efficacy of radiation has a maximum possible value of 683 lm/W, for the case of monochromatic light at a wavelength of approximately 555 nm (green)"

https://en.m.wikipedia.org/wiki/Luminous_efficacy

He's using the Cree Product Characterization Tool for his "800lm/W" without understanding that it's a spreadsheet tool, and not a specification.

Samsung LM-80 test data has their chips maintaining 70% brightness for at least 93,000 hours (~10 years continuous)

---

186lm/W is a meaningless measurement for a red led. Cree XPE-HE 660nm radiant efficiency is on par with Osram SSL and Samsung LH351H (~59% radiant efficiency)

---

Hybrid lighting systems historically refers to mixing LEDs and HIDs to get the benefits of both. No idea what hybrid spectrum is, or how it could possibly be 'new'. What, multiple wavelengths?

Ok. Back to COBs and QBs.
