Has anyone tried KD's $2.79 K2?

Hey guys, I just bought this emitter from KD and was wondering how much I should expect for it to output from 3XAAA Ni-Mh? I just saw that it is warm-white and but my order has already shipped out. How many lumens should I expect it to put out with 3XAAA Ni-Mh driving it? And for how long should it last?

i think this one is the same to DX sku#4348.
if you look here - http://www.candlepowerforums.com/vb/showthread.php?t=144087
it should be alrite in mag 2D direct drive with single 18650 cell.
I drive my cree P4 direct with single 18650 cell with H22A hs and it was very2 bright with no heat issue at all.

Any idea why the Kaidomain one is so much cheaper. At about half the DX price? Maybe a clone?

i have received from kai sku#2308
and it's the same from the GB that i got
for $9 each!
And Kai's sku#2308 is the same with
DX sku#4282.
( this is just for comparison as this
discussion is not related to your topic
which is Lux K2)
