thanks.....one thing though
could you elaberate on Vforward and Iforward ((If Vf)?!
Put them all end-to-end (in series) and put a 1k resistor in series too.
That should light them up with 3.6mA. If you want them brighter, use a
lower value resistor, but too low will cause them to fail. The lowest
you probably want to go is 220 ohms.
