https://evandesigns.com - this is the site that I buy all my lighting supplies from. I know that you guys buy from fiberopticproducts.com and thefiberopticstore but evan designs sells very specialized things that you cannot just find anywhere. I highly recommend them for your next impossible project. I hope this will help someone.
I'll have to check it out.
I am also a fan of Lighthouse LEDs, they have a good amount of niche things, and a nice supply of call it lazy pre-wired diodes (life saver when you're using Pico Diodes). I really like their LED Drivers too.
Looks like Evan Designs has Z size too, which I'll be keeping in mind when I need to order next.
