Joined: 28/11/2007(UTC) Posts: 7,580 Location: Montreal, QC		I had the idea of using yellow LED strips in the smoking section of my 60s and 70s coaches and bright white for the non-smoker's section I know that repeated smoke would have yellowed the light covers, but I don't know if it would be that visible from outside. What do you think about this idea? Regards Mike C

You could try on one coach to see the results. I have seen warm white and yellow LEDs where the difference is not as much. Think they came in a LED strip but I forget the manufacturer. David
		Take care I like Marklin and will defend the worlds greatest model rail manufacturer.

At that time the air was often dark with smoke in many public spaces and that haze filters out a lot of light and changes colors.. I think the idea is brilliant.
		Regards, Jim I have almost all Märklin and mostly HO, although I do have a small number of Z gauge trains! I have models from Era I to Era VI, but I try to focus on Eras I & III. Whoops, that one got away from me. Let's just say I focus on cool trains, regardless of the particulars :-) So many trains and so little time.

Just get a Rosco gel swatch book and add a gel or 2 over the light to change colour temperature. It will also drop light output a bit as well. https://www.bhphotovideo..._Cinegel_Swatchbook.html https://www.bhphotovideo...els/ci/1329/N/3662541030 I think Rosco 3443 Quarter Straw (Mired shift +42, transmission 81%) or 3409 Roscosun (also, Mired shift +42, transmission 81%) would be a better colour. It's leaning a bit more to a coffee colour (I once cleaned the walls of an office from decades of smoking (not me)).

LED Light Choice Interesting comparison Ross. I have both of these lighting kits, and have been fitting them on the basis of warm white/yellow for older trains to represent tungsten lamps, and cool white for newer coaches that would have been fitted with fluorescent lighting. I wonder if the first class sections of the coaches you are showing would in real life have used fluorescent lighting?

Joined: 04/02/2011(UTC) Posts: 2,583 Location: Paris, France		Hi Mike I suppose the choice is more between cold white and warm white which you can find easily (5 m rolls with self adhesive) I have noticed that what is critical for the ambiance is the painting of the interior decoration and the selected colors have a tremendous impact on the looks Here are some Märklin coatches that are using warm white LEDs strings The car in the front is standard Märklin lighting Note: some stained glass paints (Vitrail by Pebeo) allow fun effects I also use special LEDs for Xmas with integrated IC and light change for adverts Cheers Jean

Joined: 25/09/2006(UTC) Posts: 839 Location: Sydney, NSW		Hi Alan, I would never use the Marklin yellow LED lights again because once you put passengers into the coaches with yellow lights they all take on a murky dull look. I have started to use clear acrylic paints more to change the colour balance of the light output and I also dim the lights so they are less bright.
