Most of the 5mm LEDs available seem to spec 10000 to 15000 mcd. Not sure what they really are...maybe.

The other issue is that the LEDs have kind of rectangular pins and I wanted to see if I could just plug them in to the sockets Lionel is using for the tiny grain of wheat bulbs.

It is millicandelas. Conversion tool LED mcd to lumens
