model lighting- electronics question!


Recommended Posts

I have a diorama that with 4 grain of wheat bulbs for lighting- currently they are all wired to in parallel and running to a model railroad transformer (wall power, 12v output).  Is there a way I can connect these to battery power?  I have a show to display at where I won't have access to electricity.  

 

Any help is appreciated!

You can use batteries for your power source exactly the same way. There are holders available to allow you to mount multiple standard dry-cells in series to arrive at the necessary voltage. Eight, 1.5V flashlight batteries will provide 12V DC.

Larger batteries (D cells are larger than AA cells) will last a lot longer powering the same load, if you have room to hide them.

You might also want to consider replacing your incandescent bulbs with LEDs, which use much less current and will give you dramatically improved battery life.
