I didn't read your full post, but I have grown with LEDs and have to say that they are very 'fun'. But, I think they are still in very early stages of development, using them requires you to almost work with them. What I mean is that they are still being tailored to growing specifications and grower's with them have to adjust their plants and lights to work together.
I grew with the chinese models and found that they help the plant grow as a whole rather than by height or yeild. It's like they are water to a sponge where as HIDs are more of water to a balloon. If used correctly, LEDs are great lights.
I do not think their selling of point of 'requiring low wattages' has been perfected yet, simply because they aren't perfectly constructed for plants. Introducing the blue/red only spectrum has helped, as well as the size/layout of the bulbs. But, you constantly have to make sure the plant is in a neutral state; the canopy has to be open and "willing" to take ambient light rather than with HIDs, which penetrate and flourish.
Most of what I just said is jargon, but I hope it helps. Gl.

You can get some pretty good 15w ones from china on ebay. They have two main versions. Ones with SMDs and normal ones. The SMD ones are like 10x brighter, but they cost 2x as much as the 15w ones. They look like they work pretty good though. I've experimented (and even sold a couple) 15w ones. They're eqiuvelant to a 75w CFL IMO, but they spread light out better.

But you can get the same panel pre-fabbed for $100 less on ebay.
