Bah.  Lamina doesn't so much sell LEDs as LED arrays.  LED products
that achieve high brightness by superior heat management of conventional
technology are only slightly interesting. The closest thing they have
to a simple LED produces 120lm at about 5W dissipation, making it pretty
much in the same ballpark as the lumiled Luxeon V (both have multiple
LED die.)  More here:

I'm not sure who's winning the lm/watt contest these days.  Cree claims
to have 86lm/watt, but not in production parts.  The 5mm LEDs are 
getting
insanely bright (35cd), but lifetimes are apparently pretty short.  
Sigh.
