Its obvious you're not listening to what I'm saying so you're argument is invalid no matter how well you word it. I said nothing about the cutoff having anything to do with light output. That is just nonsense. LOL Like I said before, the DDM bulb's light output point of origin is the exact same as the halogen bulb it replaces so the beam pattern and cutoff is unchanged. I have been using DDM bulbs for years. Putting these HID bulbs in a standard halogen refractor style housing is a different story. In doing that, the light output is tripled in most cases with the DDM bulbs and with the stock halogen bulbs do not blind people mostly because of color temperature and light output. I'm a welder by trade so I know a bit about light output and usually when I'm using higher amperage welding current, I need to go up (darker) in my welding hood shade. I can take a picture behind the welding shade lense to prove to you the difference in light output between the HID bulb and the standard halogen. The HID bulb is much brighter than the halogen. Now I think you need to restructure your argument to make valid points.
You my friend are the one who is not listening.
You say that my argument is invalid? I bring up points that are
indisputable.
1. Putting a HID rebased bulb in a halogen projector will NOT achieve the same beam pattern (maybe close but not exact). Despite you believing that simply keeping the HID bulb capsule in the same spot as a filament. This is a common belief among those uninformed and for those who believe in "marketing hype" by the retailers who take your money. Again I say, the optics are designed around a halogen filament light source. Once you change it, it distorts and changes focus.
2. Higher lumens does NOT always equal better in a projector body (or reflector). Its all about the focus of that light.
3. Color temperature and light output have NOTHING to do with blinding people. That would be due to excessive glare caused by a improperly aimed low beams or out of focus beam pattern.
Can you please post those comparison photos? Like I said, this argument can be laid to rest once we examine them side by side.
Just to demonstrate some examples, here is a halogen projector with a 9006 rebased HID bulb inside. Wow there is a cutoff so it must be just fine right? Wrong. The beam is horrible. Notice the hot spot? It should be tight up against that cutoff edge and its bottom half should be shaped like on oval. But instead this hot spot extends well below that which now becomes excessive foreground light (which is not good on the eyes). The width is crap. And there are various dark spots underneath the beam.
And here we have a genuine HID projector with what a proper beam pattern should look like.
And this is another halogen projector with a HID rebased bulb inside. We see a cutoff again but there is a problem. See the glare above that line? Craptastic.
