interior lights

Get some black craft paper and paste it to the walls. Alternatively you could try painting it flat black inside. The LED reels are good for buildings,especially stuck to the roof where they shine from overhead. Make sure you use warm white or yellow if you like that effect. Off a 10-12 transformer tap put a bridge rectifier in series to make a DC buss. Then power all your buildings from that buss line. You will have to solder a bit to use the strips but they work well in my experience. If they are too bright you can cut down the input voltage from the transformer or add a resistor in series to vary intensity to each individual building.

We live in an old church and we keep it brightly lighted at night to show off the stained glass windows. Inside they look different during the day as the sun moves.

Simplest solution is use a cheap transformer and lower the voltage until you are happy. Different light sets will need different voltages but I would think several buildings could be wired in parallel off the transformer.

Wiring a few buildings in series will also do this for you but the down side is figuring out which light went out - like the old Christmas light string.

There are several threads about lighting rolling stock, the same adjustable power supplies in those would also do the job.

Unless the building is really dark, you have to make the interior impervious to light. Aluminum foil or black paint on the interior are two choices. With lower brightness you can still have light coming through, just not as much. Led replacement bulbs are very directional and hard to get even light distribution. The strips work very well, but you can't do it without some electrical work.

Years ago I built a Rico Station kit. I divided all the floors and made separate rooms using black Evergreen panels. I then painted the interior walls black. I made false window coverings from stock paper. With different sized bulbs installed it took on a life of it's own in a darkened room. I took almost three months and $$ to complete.

I think lighting from the ceiling helps with even lighting.

LED's can be used with your current experience. Variable DC supply for building lighting, bayonet base, and LED's that are plug & play with a bayonet or screw base.

You can get those with a flat top which diffuses the light more evenly.

You probably won't have to replace LED's.

thanks for input.  going to create lots of labels

DC VOLTAGE ACCESSORIES13.6VDC

DC VOLTAGE ACCESSORIES 3VDC

AC VOLTAGE ACCESSORIES 18VAC

I GOT SOME STUFF THAT NEEDS DC WHAT YA GONNA DO IT IS WHAT IT IS

looking as you suggest covering or painting interior, does not make sense to go to that much trouble and have the whole bldg glow!

now if i can find them that is the incandescant bulbs that have about 12" wire already and they are little bulbs,  kind used in lamp shaded bulbs street corner lights

i kind of like them

AC VOLTAGE ACCESSORIES

Well that works, not much heat. Grain of Wheat  Town & Country have them  50 for $30.

Check out forum sponsor Evan Design.  May solve your problem!

The light bulbs will burn out and need replacing. The LEDs should last a very long time. I highly recommend the LED lighting strips or individual LEDs. From your 13.6 volt tap,install a bridge rectifier as a voltage dropper. That will give you a 12VDC buss for the strips,which require 12VDC or less. 

Dropping voltage with diodes is explained here

Or if you want to use individual LEDs,they can be wired in series off the 13.6 volt tap with a resistor. That is explained here

If the LEDs are mounted on the roof and shine down,they should bleed through the building much less than a light bulb floor mounted since the LEDs have a 140 degree view angle.  A light bulb has almost a 360 degree view angle and would need a reflector for efficiency. Each 3 LEDs would use only about .25 watts of power and generate little heat.

went to the town and country web site and they have quite a deal on the wheat bulbs box of fifty for 30 bucks..  so why not bought a box, now to find the lampshades, i like to put them over back doors on buildings, looks appropriated, and i have used them all over my first tiny layout

i used two of them with lampshades on the front porchof  my country store. yeah they burn out once in  a  while  

 but where can i get the lampshades
