10mm LED for LFO

I'm building a DeadEnd FX Definitive Phase (build docs: https://drive.google.com/open?id=1gxmU0S1H5DVRIbwZ-gi_n3PO44yy-U-8) and I'm having a hard time sourcing the LED that's used for the LFO. The recommended part is a VCC VAOL-10GDE4 which is a 10mm green water clear LED with 570nm wavelength and 350mcd luminosity. The part is out of production and I can't find it anywhere and I'm also struggling to find alternatives. The closest I'm able to get is a similar wavelength but with only 100mcd luminosity. I wanted to ask here in case anyone has built this in the past or has used that LED and knows of good alternatives.
 
Thanks everyone. I saw the one at Tayda too and I'll likely grab one next time I place an order but it's rated at ~14000mcd luminosity while the LED spec'd for this build is only 350mcd. For those more familiar with their usage in LFO circuits, would I be able to use it as is, or would a simple modification to the resistance into the LED be required to make it be dimmer?
 
Did you ever find one? What did you use and how did/does it work?

I'm in the same situation, same project. I've been looking into alternatives. VCC, the manufacturer of the VAOL-10GDE4 also makes a 5mm version, the VAOL-5GDE4, that is also 570nm, but a bit higher luminosity at 380mcd. Mouser carries them. My thinking is that the light output and wavelength matter more than the size. I think I'm going to give it a try. I'll try to remember to report back if it works but this project is still in its infancy, behind a couple of other builds...

Hey, I actually bought the 5GDE4 as well and it works but I can’t say how close it is to the original. I also haven’t boxed it yet, so I haven’t tested it properly.

I can also pass along the recommendation from Dino at DeadEndFx, which is the Kingbright L-1553GDT - 5mm x 5mm square LED. Its lower luminosity but much wider angle (110 vs 30 degrees I think). I’m going to get one and try it and will compare with the other options once I finish the enclosure as well.
