Find a bias LED foward current needs?

I have a bag of infrared LEDs negotiation I am trying to wire. I have 3 legs composite by 6 LEDs in parallel. The legs are connected together in series. The LEDs Epoxy acrylic sheet. I have an old AC adapter 5.3V emitted unloaded and qualify for the output of stage 1. I also have a 25-Ohm Potentiameter and assorted resistors. I do not know the bias voltage or current needs. My multimeter RadioShack 1.1V read about in the diode test, but I have yet to see that get less than 1.2 V in various experiments I have done. How can I determine the intensity and voltage that can be run safely in these LEDs? I'm trying to optimize brightness without wearing out too quickly. Thank you! In addition, the specifications a Radio Shack IR LED is 100mA and 1.2V.

A good objective value of an unknown LED current is 10 mA. The voltage of the unit depend on the color, red would require lower voltage than the yellow or green. Use your AC adapter with a series resistance of about 400 ohms to see the LED's, which provide enough current to light without cooking. LED Running in parallel is a bad idea, the current between them is likely to be unbalanced. To use the adapter to run eighteen of the things, I suggest that pairs wired in series, along with proper management of the current resistance (about 200 ohms) for each pair, resulting in a total current consumption about a tenth of an amp, so your adapter will do nicely.
