Anyone know anything about this one. 5 watts and it says it has it's own driver. What am I missing?

Maybe it's just that it's from Hong Kong, seems too good to be true.

Either the guy is dishonest, or he doesn't know what he's talking about. From the lesser pic he's showing, I think he's selling a LuxIII Green. I have never heard of a hi-power LED in on a star circuit board with a built in driver.
Also, do the math. 1050mA (Round down to 1A) X 3.4 - 3.6 (Generously rounded up to 4v) = about 4W

You over estimate my FLOWERS!
He's giving the Luminous Flux for a Lux V, but the Ratings for current and Voltage of a Lux III.
I would ask what the numbers are on the back of the LED...
It's hard to tell from the super blurry photos. You can usually tell the difference between a V and a III by the shape of the wafer, and of course the size of the backplate. To me those look like Lux III's in the pics
In one pic it looks like it says luminaled or something like that.

After looking at it, he's selling cheap knock offs and using Lumileds (Philips) LEDs as a stock photo in the item description.
They're "Lux III" HK specials...
Avoid.
Just buy a Seoul P4 Green LED. They get pretty close to that brightness.
