This is the one I got. (I see the price has changed, I paid €18,20). It has a fancy RF remote, the advantage over IR being that the controller can be hidden anywhere, there’s no need for a direct line of sight or pointing the remote somewhere.
LED strips come in many variants, different types of LED’s, different amount of LED’s per meter, single color, or RGB. With the RGB types many light colors can be created with a remote control to simulate different ‘moods’ or periods of the day.
Some RGB strips have separate R G B LED’s, alternating on the strip. They are often somewhat cheaper, but the drawback is there are less LED’s of one color on the strip and it is hard to create pure white, cause the different colors are separated, they are 1.5 cm apart on the strip.
Then there are the strips that have multicolor LED’s. They can generate pure white cause with these every LED has RGB and if all three are on the result is an even white. Also the light output generally is higher, all 300 LED’s generate all three colors, in stead of with the previous mentioned strip just 100.
There are also strips available that have a white LED alternated with a colored or an RGB LED. These are sort of a combined white- and RGB strip in one. Can be nice, but again the amount of colored LED’s is half of the normal amount so the color light output is less. An alternative can be to use an RGB strip and a separate white strip for higher light output and to create more gentle subdued colors.
Prices at Aliexpress vary from $5 to $35, dependent on package content and LED specifications.
A wooden frame is mounted over the layout. Admittedly this does not look super, but it doesn’t look that bad either. The LED strip is placed on top of the frame and it lights the ceiling. This way the layout is lighted indirectly. This gives a nice even subdued lighting and I don’t get blinded from looking into the LED’s.
White of course gives the best color representation (Note that the walls are a shade of green/grey, so that does not look white, but the first attempt for some polystyrene station platforms are white). Quite a few other colors are possible and also the light intensity can be adjusted. Not that these saturated colors are useful in any way … but it is possible to play with different softer shades of blue or red to simulate evenings or mornings.
