There is a small amount of blue in the spectrum and I suspect that it's enough to avoid issues that might crop up if there's not enough blue. Mars is in the business of making grow lights so I'm assuming that their lights won't cause that kind of problem.

Re. PPFD maps - I haven't seen anything but the numbers that Mars publishes have been pretty close to what third parties come up with. Their numbers for the 2020 SP3000 matched what cocoforcannabis came up and it matched my numbers, as well.

In this case, I definitely need to understand how it all work in my tent and I would test it in conjunction with my 2020 SP3000.

"Though with two you can get the spread right."
Agreed and I'd only have to run them at, what, 60% power?

On the other hand, that's 2 x $280 and is adding a second flamethrower worth an additional $280? After all, I do have a regular SP3000 that's "looking for work".

The proportions of blue and red looks very much like what i read in a study about ideal greenhouse supplementation 1:20 blue red ratios. Im fairly certain that this light is for that purpose (but dont care enough to argue about it) but maybe Mars have just thrown it into their growlight section to see if anyone bites. This is almost looking like blurple, without the blue and a small minimal amount of green, dont know, maybe its enough. After all Mars is the Grandaddy Blurple. Id avoid or get ready to supplement it. Also the plant tend to need more reds than just 660.
Id check a bit over at alibaba to see if this is a rebrand aswell, and what the original sells like.
