LED grid illumination

Mouser also has them on backorder with a date now: https://www.mouser.de/ProductDetail/Adafruit/3444?qs=AQlKX63v8RvKKJjQZ2tLGw%3D%3D

Hello,

i am also looking for an LED grid but the Sparkfun is out of stock? Which one is the best to buy for a dark field microscope? And where?

I am located in Indonesia but have a friend coming from Austria in a couple of days. The backorder date from mouse.de is start of August. Any tips?
