BTW the reflectix won!
And I settled for Ledengin 15W emitters.
Can't help it, I trust nothing and test everything.

Guess that makes me a professional goof off.
My amateur opinion is;
Go with the t5 until the are past the stretching phase.
It's very hard to start 'lings with leds.
Most folks keep them too close and fry their plants, then claim that leds don't work.
Most commercial leds have a too high R:B ratio and will cause major stretch regardless of distance
Adding blue does not help, unless you back way off on the red.
I found it tricky, and being cheap and lazy, just threw a CFL at them for the first week or so.
This last batch are getting sunlight, with an LED array in the evening just to lengthen their day and keep them in veg.
Our tropical nights are a tad long and Indica's bolt to flower straight away without light extension.
Thinking about just giving them 2 hours of LED in the middle of the dark cycle so I don't have to keep resetting the timer as the planet wobbles.
(Did I mention lazy?)
Google "Discussion of the pragmatic application of LED's"
There's some good stuff there.
Aloha, enjoy

Weezard,
I am lacking in your electronics skills, so I am leaning towards a pre-fab led unit like the Kind K3-L600. I see from the photos that this light appears to be more for flowering versus vegetative growth. What would you recommends in terms of LED lights for the veg phase?

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,

Does such an LED light device exist? Dorm Grow doesn't dim, I am not sure if Kind dims their reds either. Hmmm...
