LED strip with 640Ma draw via a Boss TU3, from a VL PP2+?

Hey, I've laid out my pedalboard build, for which I've just started soldering cables - this is my first time!



I'm using a new Pedaltrain Jr. with the vented rear, for which my solution is a piece of acrylic plastic, onto which I will mount jack and power inputs (I'll make another post exploring this).

I thought it would be cool to use acrylic plastic and an LED strip.

I sliced off the Molex and soldered it to a 2.1mm input, which I plugged into the output on my Boss TU3, which is fed by a 250Ma output on my Voodoo Labs PP2+ and (despite being 9V rather than 12V) it lights up nice and bright.

However, I now need the Boss TU3 to feed two TBP switches (albeit LED only) and the little harmonizer (current draw around 60-70Ma) which will be upgraded to an EHX Pitchfork at some point.

I emailed the eBay store and they said this strip requires '640mA @ 12V DC when running at full brightness'

What's the likely outcome of running this strip via the Boss TU3, from a 250Ma output, with a harmoniser pedal attached too?

Would the lights dim slightly to accommodate, or will the pedal lose current? Could interference or any other negative effects occur?

Sound quality takes priority over lighting; unsure whether to ditch the lights before wiring in, or not.

Thanks!

Run the LED's of a separate power supply. Your current power supply doesn't have enough power. Also LED's are nothing but diodes switching ON/OFF, they could inject noise in your signal path, so it is best to use a separate power supply.

This website https://www.superbrightleds.com/ has everything you could ever want with LED's, power supplies, etc you name it.

Ah, that's rather sad, after all the effort I put in.. but both the lack of power combined with the potential for noise to be injected sound solid.

I'm surprised, the LEDs run fine from the Boss TU3 at present, which consumes up to 80-90Ma itself and is connected to a 250Ma source, so therefore must only be giving the strip 200Ma?

Nonetheless, any potential for noise in the name of aesthetics is a no-no.
