I completely agree and don't fault you for not understanding that color is not an indication of quality when it comes to pink light considering how much group think is involved with the cannabis forums. Here is a quick question. Why is it that Cree doesn't recommend COBs for horticulture?
Cree XP-G3 in 3500k with 190 lm/w or COBs with what???? 120 lm/w? COBs are easy, cheap for DIY and they work. nothing more. They are not the highest standard nor where the industry is going in the future.
Blackdog sells garbage and passes it off as quality. They used Epistars and said they were top of the line. Cree licensed that tech to them years ago and moved on. They are lug diodes which are definitely not top of the line.

They must not know about COBs though.
