The leds in the lights your using are from Bridgelux. Bridgelux is an Osram company.
LED, light source manufacturer of LEDs and arrays for Solid State Lighting applications
They are producing the led here in the states and than selling them to china. At least that is my understanding. Therefor making your claim that china is the home of led production, incorrect. In addition Nichia and Osram both make the vast proportion of there product here in the states. I have a friend that is a rep for one and a business acquaintance that is a rep for the other so I have a pretty good idea of what I am talking here.

You have showed my a link to China made lights "www.ecogroled.com/".
That isn't a link to the 420nm led you were referring 2. In addition Those Prices suck!(90watt led for 299$). You can get the 90watt ufo lights from amazon for 150$ and I got pricing right from china for 90$ each. So what give's? Have you found a 420nm high power led? Or was there just some talk with your "supplier" about using them?

ANYONE LOOKING TO BUY THESE LED LIGHTS GO HERE.
LG-LED Solutions Technology Limited - Led grow light, commercial light, led bulb
For get ebay...Don't bother those folks in china if you just want one. But if your looking for 4 or 16 led light contact them and they will give you factory direct pricing.
