I can't see that it's for either.

What I do see is marketing.
And we have a winner of the "band wars".

Seriously, by experiment, I find no need for more than 4 "bands" at the most.
And 2 of them are not really necessary, (they don't return enough bang for the buck).

I use 660nm. red, and ~460 Blue.
Those are the "bands" that ganja listens to most intently.

Some "strains" do not take kindly to leds.
But those plants do not "like" full spectrum CFLs either.

Find a light that uses the most efficacious color frequencies with a high R:B ratio.
Then choose the one that lets you dim the red and you will have one lamp suitable for both flowering and vegging.

And you get to tell it which and when.

Hope that helps,
