Re: [Z_Scale] what voltage of grain of sand needed
For white color is generally 2.2v and 20 mill ampere this give you a +-480 ohm resistance for a 11v input

Subject: [Z_Scale] what voltage of grain of sand needed
i was wondering what voltage of a grain of sand light bulb is needed to replace the original lights in a marklin engine would it be 1.5v, 3v or 6v? im sure its not 12v since each light has a resistor in series.
