Hi Guys,

I was thinking of using ultrabright 5mm LEDs for my power indicator with my 3PDT true bypass stomp wiring. I've seen 4.7k quoted for normal LEDs. How do I calculate what I should use instead? Does its luminosity (1000mcd vs 4500mcd) affect things? Are there any other considerations (other than price) I should be taking into account?

As always, many thanks,

ff

it doesn't really matter. all a matter of taste and how bright you like 'em. 5.6k should be fine. go lower if you want it brighter and higher (10k) if you'd like it less retina damaging.

I find you can go 15-18k and still see it easily with the high efficiency/superbright ones: I always understood a higher value resistor made switch pop less likely.

I have used 18k on some of the really bright ones.You can do a quick simple test by connecting/touching the led and resistor in series to a 9v battery

or wire a pot in series with the led, set it at the brightness you prefer and then measure it.
