That being said, X-Treme power should be significantly brighter than older, traditional designs like Osram Silverstars (what I have one one of my cars now). Will be shopping for Philips X-Treme Power or Osram Hypers soon.
What are HIR bulbs? Are those the ones that have standard wattage but have higher output per wattage (at the cost of service life)? I've heard of the +50 type bulbs from Philips, Narva, Osram, etc...?
