Good info... It's been a while since I've had to apply Ohm's law to anything!!! I found a site that sells individual diodes. They have some white 3MM diodes that are 3.6 to 4VDC @ .020 to .030 amps each. So, I guess if I wired four to a cluster in series, I would at least be OK with no resister. Actually, it would take 14.4 volts to meet the 3.6 volts per diode, so it may be better to go with the three using a 60ohm resistor...

Here's an interesting calculator I found while looking

here's the website I will probably source the diodes from, if I ever get around to it!!
