LED voltages

[jellybelly]

so i would like to break out the leds from the various places in the build and put them in a place where i can see them

but am missing some specs which i cannot find or measure

on the powerboost:

green fully charged led 1.95v
amber charging led 1.95v
blue power led 2.8v
red low power led ????

does anyone know the spec of the led on the pi zero???
