Yup....correct bulbs. As far as why they perform better, I dunno. The original design by Toshiba had a special coating that reflected IR light back into the bulb making it run brighter, but I see of the new Phillips units they don't have the special coating yet work just as well.

So I had the HIR bulbs installed today and they don't look any brighter than my stock Sylvania bulbs. I'm reading on HIDPlanet that these HIR bulbs need time to warm up to achieve maximum brightness, if so then these HIR bulbs are worthless to me since I rarely use my high beams.
