I belive those are Hella 4000. There are several lights in the 4000 series, but I have no idea what model those are though. Some of them even have there own power box aka: balast. Hope this helps a little.
Hella 4000's. There are only two types of 4000, and they come in three beam patterns (flood,spot,euro) The ones with there own ballast are the 4000HID and run ~600 per light. The normal 4000's can be had for ~100 a piece.
