kc headlight housing compared to stick housing

How much better is the reflecter of this housing compared to the stock housing?
Trying to decide if I should get it or just replace the bulb. I'm gonna go with a sylviania zXe bulb either way

Above is a thread with some pretty good comparisons. I also recently added these to my Jeep. Feel like the high beam is brighter. However, most of the roads I have been on lately all have streetlights so haven't had a chance to really compare yet.

There is a close-up photo of the housing in my profile/"garage"

I had the zXe bulbs on my Tundra and loved them!

The real question about the KC housings is how well they focus (beam pattern, uniformity, cutoff) other aftermarket bulbs.

The stock housings do a better job than others of focusing HID bulbs, but its still no quite good enough for my preferences. The KC housings might do a better job. The HID bulbs are really the acid test because they provide 2-3X the amount of lights of halogen bulbs which really makes the scatter obvious and they create a crescent shaped arc source instead of a straight line filament.

What HID lights really are:

If you are buying only a bulb [not counting a replacement for a genuine HID system], you aren't getting HID.

KC reflectors are an improvement in beam pattern over the terrible stock Jeep reflectors.

No doubt there is a difference between HID bulbs vs systems and overall performance depends on the system not just the bulb. That's why it is silly to just look at the light output of the bulb as a metric, when the optics do a poor job of focusing the light.

The stock reflectors do a very nice of focusing the stock halogen bulbs as week as they may be. They even do a surprising decent, but not good enough, job of focusing HID bulbs.

The KC reflectors MAY deliver better performance than the stock ones with a more powerful bulb, but I haven't seen any evidence.

Beam projection on a wall 10-20 feet is good first indicator but it doesn't show the distribution of light over distance. For example, in the case of the HID bulbs in the stock reflectors maybe 15-20% (judging by the amount of glare they produce) of the light is scattered instead of providing illumination beyond 100-150 ft, yet many perceive that setup to be great because there is so much light right in front of them. I have a pair of 1800 Lumen lights on my mountain bike that appear to be brighter than factory HID reflectors 15 ft from a wall, but even at full power everything beyond 80-100 ft is dark.
