Yup, the NBS Depo housings are one of the very rare examples where hids have a respectable output inside aftermarket halogen projector housings. Mind you this is purely by chance and not through design as none of their other aftermarket housings deliver the same results ... nevertheless, their cutoff is clean. Depo NNBS aftermarket housings however have no such luck.
Btw, it should also be noted that cutoff is but one element of successful hid projector design ... light dispersion, efficiency, width/throw, and many other elements have to combine successfully to make critical lighting safe for the driver and oncoming traffic.
Like all lighting, be it a halogen reflector, halogen projector, HID projector, or even the rare oem HID reflector setup (see 2000 envoy), different manufacturers achieve different levels of success within the above stated parameters. Hence why there are many variations of all these types of lighting.
But in general terms, other than in the rarest occasion such as the NBS Depo example, combining bulbs with housings not meant for them will always result in either failing to illuminate the road properly, failure to protect oncoming traffic from too much light, or both.
