I'm not sure if the halogen replacement bulbs are the same way as the halogen conversion bulbs. The ones I posted look like a normal bulb, not like an H1 or such bulb. Also, they probably do not produce a lot of heat like the H1 bulbs do. So as far as the beam goes, I'm pretty sure they are just a halogen-type upgrade bulb, much like the halogen boxed bulbs that replace the incandescent bulbs.
