I'll wager these LED's just don't put out the right spectral output to ripen big, meaty Afghani buds like 1000 watt Hortilux bulbs currently do. I'll also bet they just don't penetrate deeply enough to make tight buds on the entire plant. Sure, lettuce is easy, but we're not here for that, now are we?
A few years back, I was really anticipatory over a new bright light using microwave technology. It is called the Sulfur Lamp. I really thought this was going to work, and today I came across this article:

So who knows, maybe in the near future we'll have a new type of growlight that will grow even more amazing buds than we already have using our HID's!
Dr Ganj Reviewed by Dr Ganj on . LED grow lights... input please. Hello guys, I'm exchanging eMails with a representative from a LED company. I asked him if they could produce a custom light for growing, and here's what he told me: Our options are as follow: 940nm, 850nm, 660nm, 630nm, 610nm, 590nm 570nm, 530nm, 510nm, 470nm, 460nm, 400nm and a total of 64 LEDs in the bulb.
