How big luminosity would you recommend for LED diode for stompboxes? Ive made a stompbox with some random LED and it almost makes me blind

I dont know what the luminosity is so I dont know which one shall i buy now. I was going for something like EHX kind of light, that one seems okay.
just turn the pot till you like it, then solder in a resistor. start at 10k (or use a 20k), and don't turn down to 0 or you'll blow the led.
