With the addition of the 2 extra light channels over the Gen 3's and the type of lens over the LED, it has made a substantial difference in illumination.
I can pm you the link to the article...but you've probably all ready see it

Yes thanks, I've seen it.
This continues the ongoing debate of lighting. I do wish I could afford multiple fixtures run over multiple tanks. The Gen 4's look amazing and LED's do get better every day. I ran 2 Kessil 360W and I wasn't impressed, switching to T5 36w x8 a year later. Perhaps I used them wrong, I dunno, but I saw immediate results by switching. Some folks grow SPS no problem with cheap Chinese fixtures.
Basically, for someone starting their first tank, I generally don't recommend LED'S by themselves, as that person will have better beginner results with older tech.
