Actually, most of the high priced LED's don't tell you what nm LED's they use. I don't want to bash names but one of the expensive US brands go so far as to say that their spectrums are a "secret because its taken years of testing to find just the right ones" complete hogwash! the par used most efficiently by plants is well know and can be found with little effort. the same company boosts about using 6 nm ranges including UV (A) and orange, both useless for you plant. the ratio of 2-1 before we had IR added seemed like a good middle of the road % compared to most that are 8-1.
the most suggested nm's for red and blue are 430, 470 red and 630, 660 for blue but with the way the plant uses these there is an overlap. pushing the nm's a little one way or the other is not going to make any big differences. its the power or penetration of the light. we added the IR to the second unite and it seem to be working very well with little surface heating difference so you can still keep the lights close. I do recommend the 120 degree lens over the 90 for autos but the 90 degree LED has more LUX than the 1000wt HPS/MH at the same distances and when i get more, i will get the 120 degree instead to cover a larger area whether doing clones (i put clones right on the flowering table, no veg state, or a full think different grow because on the genetics in that plant with nodes at less than a 1/2" apart.
the Apollo 8 is actually using 287wts and not he 300 advertised and is a better product then the PenetratorX in my opinion, which does include 40years of lighting experience.
I would write to Ellen (love the american names they use) you can reach Ellen at cidly26@hotmail.com
and you will be dealing directly with the factory and not an agent. My friends may get pissed at me giving out this info, but it gets under my skin that they have not used research to develope the website to sell these so I am sharing it with you.
you can see the pictures of the lights at my thread here https://www.autoflower.org/f5/crash-burn-resurrection-light-comparison-first-auto-grow-12065.html
