hmmm
well i dont know if its really 10k or not but box has written 10k with marker,my main concern was to blind stubborn drivers in fast lane not giving way with 55w hid
but as compared to low beam,visibility is much better,even in rain as well .....if it doesnt works for any1 what can i say,atleast works for me
n i have fog lights as well which i didnt replaced with hids
