how are 2012 altima HID xenon lights different from 2010 Lexus es350 hid xenon lights?

Robert

Does the Altima project it differently? I'm thinking Altima's reflected back towards the front of the car while the Lexus just projects forward.
Could I simply buy a 6500K bulb or would I need to replace the system?

Answer
I know what your talking about but this will be difficult to explain.

The Lexus ES350 has a special halo projector. Look at the front of BOTH of this picture:

Notice that there is a circle projector that shoots out the xenon lights.




Now compare this with the Nissan Altima headlights...

You will notice that the halo projectors aren't there in the Altima. (the circle projector lights)

Every car has reflectors which reflect the lights towards the road for better visibility, but the Lexus ES350 (also followed in the Toyota Camry) has halo projectors which provide better visibility during the night. It slightly works with higher Kelvin than a normal headlight bulb (I think they operate at 3K).

So basically the lights of a Lexus (with special halo projectors) shoots out vs the lights of an altima reflects inside the headlights for better visibility and then shoots to the road. Although I don't know how the lights reflect in the lexus but they are much better than standard headlights.

Lexus ES350 uses 6500K Xenon, Nissan Altima uses 43 or 4900K (I think, not sure about that).

Here is a chart of xenon lights temperature:

You need to have special halo projectors in order for it to reflect like a true Xenon.



EDIT:

Do you have the Altima?

Here's a good write up by someone I found: use this

Questions about Panasonic GT50 THX Cinema picture mode?

Alex

I purchased a 50" GT50 HDTV a few days ago and I absolutely LOVE it! The picture is amazing. I was playing around with the picture modes though and i noticed one called "THX Cinema". How is this different from the regular "Cinema" mode? When i switch between them all that's obvious is that the picture looks a bit smaller but more complete (like it zooms out a tiny bit). Of course I'm completely ignorant to all this technical stuff so what do I know. Can anyone explain this to me? I the THX mode optimal for movies and such?

Answer
For a given manufacturerâs compliant display, THX [picture] modes are intended to provide a set of simple preset picture settings that conform to THXâs carefully chosen criteria for video image quality. Ideally the preset THX picture settings should provide the most natural or accurate video image quality short of a professional video display âcalibration.â In reality, for the more demanding perfectionist it is relatively easy to surpass the image quality performance offered by the preset THX picture modes on the 2012 Panasonic plasma display panels by using the Custom picture mode along with proper display calibration software and hardware.

In addition:

THX picture modes (according to Panasonic GT50 series eHELP, page 25):

âPrecisely reproduces the original quality of the image without any revision.â

âRecommended for playback of THX disc[s] (disc[s] with âTHXâ logo.) THX mode is used to mirror the picture settings used by professional filmmakers, faithfully reproducing the image quality of THX Certified movies. (THX Certified movies have the âTHXâ logo on a disc.)â
