Whats the benefit of the planted + over the standard 7000K
In a nutshell, around one out of three LEDs that are on the fixture is a true red 660nm deep red.
So you are trading the power of the whites, for the spectrum of the reds. Reds are better for most plants(not required by all) to get their true color (as they would in the sun). It obviously changes the color of the light to a different "warmer" tone overall.
Since it is based off of the Ray II, it has lower PAR than it (again trading whites, for reds that just don't penetrate as far), and more PAR than the regular fugeray due to just having more LEDS.
Here is a #s sample for you:
Fugeray - 24 Inches 112White 8Blue 3014(type) 12 Watts
Planted+ - 24 inches 88White 44Red 8Blue
Ray II(dual 7k) - 24 inches 192white 3014(type) 20 Watts
I don't know if the LED is a different type, as they didn't disclose that yet as far as I know.
I know they are trying to place the LEDs better, but by just looking at the numbers one might guess that it is fairly in the middle in terms of strength, but I wouldn't be surprised if it dropped PAR off quicker due to the reds, so near the surface(closer to fixture) will have closer to RAY II, while 21 inches will be much closer to fugeray. This of course goes out the window at least slightly if they used a new and improved LED type which is a possibility.
Here is some evidence that points in this direction:
