Using UV LED for an on/off indicator

[ironman180]

Hi guys!

Another noob question incoming...   
I tried to google my problem but couldn't find anything close to what I want to know...
I have some nice UV LEDs and I want to use one of them in one pedal I'm building as a standard on/off indicator. Is it possible for UV LED to interfere with the pedal or the other pedals on the pedalboard (e.g. excess noise or something similair)?
The pedal I'm building is Acoustic 360 fuzz.

Thank you for you help!

Are you dealing with Soft, Intermediate or Hard UV..??

I have no idea... How can I check that? Because I didn't buy them but found them.

Don't know if this will help to determine if it's soft, intermediate or hard UV...

ive used 3mm uv leds in pedals, (just for the purple) no problemo...

What people are saying is there are three kinds of "UV" LED. One (soft, around 400nm) you can see, it looks purple, it will work fine. The other two you can't see as well but WILL cause eye pain or damage, like a tanning bed without sunglasses....no bueno. You may see some light, but not the UV. "oh, that's not so bright....in the visible."

There is no safe and easy answer if these are unknown wavelength.

Here is a longer take:

Sorry, I have nothing sensible to add.

YES you can use them, but they ARE NOISIER. metalloids playing bonged out of their minds at 30,000% distortion likely won't hear it, but they can be an issue in some cases. use a bigger clr and proper filtering to the power supply and you should be fine. make sure there's a snubber in the power supply, 1n-3.3n should be sufficient to nuke any noise from it.

if you turn your guitar way down and it starts making mating buffallo noises, or turn your guitar off and it hums real loud, you may have to add a bigger cap to your power supply.

unity gain stuff it shouldn't matter. only seems to add noise when stuff is gainy.

for amusement's sake, definitely try them as clippers, with germanium in line with them for extra points. they have a weird voltage they run at you may find sounds kinda cool

UV light can really hurt your eyes, but you won't notice it until you close them.

i might use my Deuterium lamp for an amp indicator, haha, blind the whole room with strong UV, while everyone thinks its just a weird murky purple colour glow.

cheers
