not many companies list lumens. i'm trying to figure out why? i think all the cheaper companies can just list kelvin temps and the higher the better people will think they are i suppose.. i am just running 6500k replacement bulbs and it's better than stock and are only slightly bluish. i'd love to just turn those fog mounts into scoops. that is unless some company wants to make aftermarket fogs/driving lights for the stock location.
