Anyone have anything new to contribute to this thread being that led's have surely made another technological leap? 
@Growmau5 , come on bro - bring some of that ChilLed tech into this thread and let's see some up close and personal performance over top of some greens.
I know you have the means to make this happen

What is your spacing center to center? 24"Learnt a lot from this board while researching building an LED fixture for growing 'conventional' plants, and I'm excited for the opportunity to contribute in this thread.. Setup is a 4x4 with a quad Vero 29 gen 7's running @ ~320W from the wall.
Your fixture is also 24"x24" in that 4x4?

I was off for the summer while my power rates were up. But i am back to the grow. I missed this thread. I am using LED to grow my lettuce, but I have a bunch of cobs and heat sinks around, so hell, I do one from scratch. Ill put something together over the weekend and post some pics.

Rosemary and lettuce, My Aloe loves LED, gonna have to chop it soon I think, getting too big for its pot.
Baby buzz button plants and another lettuce...
These are growing under a single 90cri 3000k home made strip using cobs, about 20000 lux at the plants distance from light.

are you running cobs here? if so, what K are they? the head looks great BTW, no tip burn, a nice head is forming, it looks like its loving that led light. Do the leaves feel thicker to you? I ran some lettuce under 3k cobs once and the leaves got really thick, it was weird.

These are cobs, 3000k 90cri. Using a new organic soil mix, will be interesting to see if tip burn develops. Ive had bad luck with it in the past... Im not familiar with this variety of lettuce so cant really tell you how it would grow outside but it seems happy so far. Here is a measure of light intensity taken with my cell phone about plant level.

It looks to me like it is developing the "Flower Effect" for lack of a better term.
The new leaves seem to be getting smaller rather than larger. That is exactly what I have been seeing with most of my led attempts.
What is light height from tops ?

what?................every local lettuce/microgreen op that retrofitted to t8 leds from fluoros has been loving them, same yield at half power and lower temps,no bulb swaps for yrs, ROI is quick.
