Reply to blue led burnt - what mcd?

hey guy.

i just connected my vci and the bottom most left button blue LED is broken. if i switch it on or go in juggle mode it stays unlit. otherwise it's normal green, so i'm guessing it just burnt.

is it possible that a LED burns just like this? i didn't do anything special nor recognized something.

no biggie since i got some soldering experience. i did a quick search to find the how-to-change-a-button-led-tutorial and some informative threads (i know i need a 3mm led) but still got one question:

what light intensity (mesured in mcd) do i need to buy in order to have the same intensity as the other blue leds? couldn't find any info on that..

thanks
