Current through one LED in series with 8.2 Ω:

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

8.2 Ω is a standard value in the E12, E24 series, so it comes in almost every resistor kit.

Same first two colors, different multiplier:

What are the colors of a 8.2 Ω resistor?

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

What is the SMD code for 8.2 Ω?

8R2 on 3-digit resistors and 8R20 on 4-digit (1%) resistors.

How much current flows through a 8.2 Ω resistor at 5 V?

610 mA, dissipating 3.05 W. A 10 W resistor is enough.

Which resistors get mixed up with 8.2 Ω?

grey, red, silver, gold is 820 mΩ and grey, red, black, gold is 82 Ω: only the third band changes, so check it carefully.
