Re: Using LEDs to light model train layouts

yes I start with only white LEDs.  White LEDs are really blue plus
some chemical trickery.

starting with white LEDs and adding acrylic paint I am able to produce
lights that range from fluorescent looking to incandescent looking -
as you can see in my photographs of the results. (and they do look
better in real life than the photographs)
