BMW Adaptive LED Headlights 2013..

hi there, if you could help, does anyone know the Kelvin rating, or a good guess at what the new 2013, and some 2012 BMW LED Adaptive headlight lighting is please?.

not the xenon, just the LED rings like really.
they look very intense, more than 4300k usual in most cars.

they do have a touch of slight blue…
some say 5000, 5500, 6500…
seems even BMW are not so sure either.

kind thanks.
