Over the summer (downunder) I fitted lights to all my passenger carriages and station buildings.
I’ve ‘standardised’ on using ‘golden’ white LEDs from this source:
And 9V ‘PPS” rechargeable batteries.
The batteries are removed for storage and charging. They are claimed to be 300 mAh but I’d say more like 100. Anyhow, that’s more than sufficient using these LEDs, which give quite a good light at around 5mA. So even my sleeping car with a total of 12 LEDs, takes only 13mA total.
The golden LEDs give a great light. In this pic the headlight is a ‘normal’ white LED and the internals are ‘golden’ ones.
Melaleuca station has 3 LEDs under the awning and 3 internal. The closest pole light is grain of wheat, and the distant one is a LED.
Lilyvale station has 3 golden LEDs in the building.
I used ‘normal’ white LEDs shined into the ends of 50mm perspex to simulate fluorescent lights in the dining car.
this shows 2 compartments in my sleeping car. The right compartment has a ‘blue night light’.
this video shows some more of my experimenting with night video. I tried getting my grandson to shine a torch on the train but he was a bit too close. I used a flickering tea-light in the loco cab and it looks quite good,
and this is the one I previously posted:
