10mm LED Clear High Brightness 12V Volt Various Colors Constant, Pre-Wired Works from 6V to 12V Pack of 1, 5 or 10.

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. One LED will run for about 130 hours on Duracell or similar good quality AA alkaline cells. Ten LEDs will run for more than ten hours on such a battery pack. The violet type will show up day-glo fluorescent items and markers but not special banknote inks.

The brightness is still good on a 9V supply and still pretty good at 6V. Current consumption is reduced to 70mA for the ten LEDs shown at 6V, so this arrangement would run for more than 24 hours on a four cell AA alkaline battery pack.
If you would like to mix the colours in a pack, please use the MIX options and send me a site message with your list of the colours required. The yellow colour is not quite as bright as the others due to a peculiarity of the physics involved in the silicon LED process.

The batteries and pack shown for demonstration purposes in the video are not included.

If using a power supply it needs to be a regulated type. Nominally 12V train set transformers and old battery chargers providing rectified a.c. at a peak voltage higher than 12V will kill the LEDs.
