Wow, thanks for doing all that typing. Out of a catalogue?

1600mcd)

These sound like they might just be perfect. What kind of package? My
current plan is to drill holes in some small stones, fit the LEDs inside,
and
then pot with something transparent.
I could run three core to all the clusters and adjust the voltages on the
two
feeds to chose colour.
