Passenger Car LED & Window Update

GRJ,

Where did you get the new window glazing material?

I bought the sheets on Amazon, BANLTRE 12 Pieces 6 mil Blank Template Material Stencils Mylar for Cutting Paper Clear Transparency Sheet 12 × 12 inch (12-6 mil).  You can probably get them in a host of other places as well.

Why they put that green window tint in passenger cars is beyond me.  I don't like it at all.

Very nice looking job, John!  That is what I have been told in the past.  Adhesives that aren't allowed time to fully cure before putting the car together will spot, fog, or even craze the acetate or other film in windows.  Some double sided tape adhesives must fit in that category.  The 1/24th scale model cars I built in my teens and early 20s with no open windows fogged over time.  I still have a dozen of them stashed in a cupboard with no room to display them.

GRJ is using clear plastic sheets for the windows.

I believe the green tint in the LED version is because white LEDs are fundamentally BLUE LEDs that are color-shifted to appear white to the human eye.  It appears the interiors of his cars have a YELLOW tint.  Mix BLUE+YELLOW and you get GREEN!

Incandescent bulbs have relatively less BLUE energy for the same apparent brightness as perceived by the eye.  That's why his original photo does not appear as green as the LED version.

Another contributing factor may be the setting on his digital camera (where you choose daylight, incandescent, fluorescent, etc., or let the camera automatically select the light source type).  The camera software then compensates for the relative color spectrum which can shift the digital image relative to what a human perceives.  In other words, the green may not be as noticeable in-person.

If it's a deal breaker, the interior surface could be re-painted though that sounds like a lot of work.  If I were doing it, I'd experiment with the LED color whether using tinting paint on the LED lenses or perhaps switching to yellow LEDs depending on the era modeled.

Truthfully Stan, when viewing in person, they don't look green at all, it's just the photo that is apparently coloring them.  I'm also using warm white LED's, not the bright white.

I should have said why Lionel used green tinted windows.  Gunrunner John's windows are fine.
