Current through one LED in series with 220 mΩ:

Above 20 mA: too much for a common 5 mm LED.

220 mΩ is a standard value in the E6, E12, E24 series. Check the tolerance and power rating of the actual component.

Same first two colors, different multiplier:

What are the colors of a 220 mΩ resistor?

On a 4-band resistor: red, red, silver, gold. On a 5-band resistor: red, red, black, pink, brown.

What is the SMD code for 220 mΩ?

R22 on 3-digit resistors and R220 on 4-digit (1%) resistors.

How much current flows through a 220 mΩ resistor at 5 V?

22.7 A, dissipating 114 W: more than a standard resistor can handle.

Which resistors get mixed up with 220 mΩ?

red, red, pink, gold is 22 mΩ and red, red, gold, gold is 2.2 Ω: only the third band changes, so check it carefully.
