You already posted two things without him even responding to you yet, and all you're telling him is to not do it, and now you're telling to use CFLs.
Did you read his 1st post? He wants to build his own. Let him do his thing dude.
Lol, I did read his first post. But I just read a whole article on this and talked to a few people I would like to consider professionals for several hours on the topic. I know he wants to build his own. But from everything I have ever seen with my own eyes, or heard about with my own ears, has pointed to DIY LED to be a half-baked idea. LED is great, but I don't think you can do it as good as the pro's, and I don't think you can get that experience unless you spend easily the same or more on buying your own units pre built.
He brought up CFL's as an assistant light, to balance the spectrum. I personally use more CFL than LED (yes I have LED's that I use, 3rd generation 50w and 90w UFO's) because it gives me fantastically healthy growth, and it doesn't grow too fast. I always have traffic in my veg room, so I try and veg them out slower now. LED does give some more vigorous growth, for the most part, all veg plants love it. When it comes to flowering LED has CFL beat, 10:1 for my own personal use. But once again I am using HPS to flower, my 3rd generation LED's can give good flowers, but I just can't get the same weight with them, after about 12" the light isn't intense enough, at least with my shittier LED's, another reason I suggest purchasing quality designed by an engineer with a degree in the field. I just don't think any of us could possibly get anything better than an amateur's understanding without going to school for this kind of shit.
All I want is for this guy to have success in his garden and to be happy with whatever decision he makes. DIY LED is heart-break, less than a year away. You can put that quote on your wall, because I wont be hear to say "I told you so."
I'm not trying to be a smart ass. I have learned a lot about this in the past, and just this week I had a refersher course on the new 4th generation LED's, just a day or two before I saw this post. I don't know everything, but I do know that buying a well engineered lighting instrument is going to blow some ghetto grow light straight the fuck out of the water. It's a bad idea, just like a menstruating chick in the ocean.
But seriously guys... check out these new plasma lights, so fucking tits!
