ATI LED Powermodule

ATI 60" 4x75W LED & 8x80W T5 LED-Powermodule .

Interesting! So, I noticed that the 60" version has like, 8T5s and 4 LED modules on the fixture. I'm curious, since you can easily grow stuff under the 8 T5s alone, what does adding the LED modules give you exactly (aside from a bit of shimmering) ? Don't get me wrong, it's a slick looking fixture, but if you have to swap out and replace the aging T5 bulbs anyway, that seems to negate one of the major benefits of LEDs no ?
