Pre-Wired 10mm LED Clear High Brightness 12V Volt Constant, Works From 6V to 12V

This is a pack of one, five or ten items of 10mm diameter LED with 20cm wire leads with a resistor for twelve Volt operation fitted into the leads. Nominal current at 12V is 20mA per LED. The lit pictures are taken using a 12V battery pack comprising eight AA cells.

Operation down to 6 Volts is entirely possible at somewhat reduced brightness. The current draw at 6V is reduced to about 8mA.
