I'm going to go in order of post to try and keep this straight for my simple brain.
KJC: Those numbers given by EH (aka Jeff) is where my differences with him have been prior to him making Area51 lights. He believe that plants require high amounts of greens and yellows for good growth. He also thinks that 630nm is the better choice for the red spectrum. While I will agree that his panels work better now than they did as red and blue diode panels, the reasons may be different that what he thinks. His warm whites add more 660nm red and more ~440nm blue than his old panels had IMHO.
michalciesla, I wouldn't call plantronics state of the art or top 3 by any means. They use red and blue a few whites that are all 1 watt diodes. They are very similar to the Hans panel with the exception that Hans uses 3 watt diodes made by Cree and Luxeon (ie higher quality and photon output as well as higher penetration values) and no whites (bad idea in my opinion). The light he was referring to is called the Procon 400.
jon705: While I didn't see your grow or setup, I would have to disagree that you got better results based off the information you gave in the post above. Using more power and covering a larger area you received less product. My goal with LED panels is to produce the same quantity (or very close to it) with higher quality (that's the easy part with LEDs) by using half the power of HID lighting systems. I've done that twice and I am working on getting consistent results (each strain performs slightly different so it's very hard to nail down). Your test was almost exactly half the wattage per square foot (62.5 for HPS and in 37.5 for LED) and you came out three ounces under. Not bad results by any means, but I believe it is well below what LED lighting is capable of.
Adding whites is the only realistic way of hitting all of the accessory photo-receptors that the first 2 generations of LED panels were missing. The key is adding enough white to fill those needs and still having enough left over to boost the other production wavelengths to maximize the growth rates there.

Im sure Sara could put Cree diodes in her lights if she wanted, but the price for the panels would go up quite a bit.
that thing is going to kick ass!!!
which set me back a few weeks and resulted in me flowering a set of smaller than usual plants.
