So here's my question of the week. The Wheat Kings & Pacific layout is coming along quite nicely, and I'm about to start placing buildings and wiring two additional buses (apart from track) - one for accessories, and one for night lighting. So here's finally the question - what's a good wattage light for the inside of buildings ??? I don't want them too bright, but just sort of an ambient light effect. Are the grain of wheat bulbs too small ??? They seem like they would be to me.
