I have a question.
Calculate the resistance
Before wiring my LEDS to my sound board I want to make sure I have not goofed up.

. 47 ohms, 5 watts.
That idea suddenly crossed my mind.
Is there no difference of 1 % from 5 %?
Let's take an example.
I'd like to buy 1.2 ohms, 3 watts.
Don't you care about the next 1 % or 5 %?
