I have the regular halogens lights in my car & I did a little experimenting myself. I bought the HIR high & low beams & the Xenon 7k "high beam" bulbs. I did not have any comparison pictures that came out, but I did note a few differences.

The HIR lights are significantly brighter than the stock bulbs (high & low). The Xenon 7k is significantly bluer than the HIR & stock high beam bulb. I don't think the Xenon is as bright as the HIR bulb. The blue coating is pretty significant & probably blocks out some light.

Because the Xenon bulb wasn't brighter and didn't match the HIR color, I put the stock high beam bulb in the fog light. The stock high beam bulb is much brighter than the stock fog bulb & matched the HIR well enough. All in all I wish I had ordered 2 extra 9011 high beam HIR bulbs to put in the fogs.

The end result with HIR's in the High & Low beams & stock 9005 in the fog light is significantly brighter. I haven't been flashed by any oncoming traffice despite the increased light. I doubt I'll consider HID conversions now. Since this is my first new car I was pretty happy even with the stock light output, but I'm easily impressed. I've been driving work trucks (F150 & Chevy Astro Van) for years or my personal cars (74 Bronco & 83 Porsche 911). I upgraded my personal cars w/Hella 7" round headlights that use a replacable halogen bulb (don't know what number) I think its kind of funny that the Bronco & 911 use the same headlight, it has to be the only common part.

I guess the only comparison I haven't seen is Sylvania Ultra compared with HIRs.

Also, the only adjustment I needed to make to fit the HIR bulbs was to grind down the mounting "ear". One web site shows an adjustment to the plastic just behind the bulb and infront of the o-ring. This was for a Magnum, but the bulbs fit my C with much less work.
