I understand the black housing MUST take off some output or why would the OEM's be chrome? But anyways the reflectors must have something to do with it, there is no way that 8 chunky reflectors equals like 100 evenly spaced OEM reflectors...But what gets me angry is that the picture of the seller shows it with the OEM reflectors! I emailed them and I'm awaiting a response. I will be posting up output pictures tonight.
