Default JDM/EDM projector cutoff question

I did a quick search and didn't come up with an answer.

Is therea difference between the projector cutoffs in the HID lamps vs. non-HID housings?

I'm buying a set of JDM HID housings and want to make sure I get the correct parts to adjust the beam pattern.

Not necessarily in the cutoff part per se - but halogens will be designed to put more glare through what's called a squirell finder plate which deliberately diffuses some of the light upwards from the cutoff. HIDs are designed so as to have little if notzero light going above (to avoid blinding upcoming drivers).. so there is an internal difference in hardware. Not to mention the location of the cutoff place with respect to the source of light, so as to ensure proper focusing
