I was hoping to draw the majority of the circuit I was making to connect 50 LEDs in parallel on an unprinted circuit board. The connections worked okay, but the further the LEDs were from the power source, the dimmer they got. There must be too much filler between the silver particles increasing the resistance. Probably okay for patching broken connections, but don't count on making a whole circuit from it.
