Any other sources for ssi-b8v521560ww strips?

I know Digikey has them for sale, but cant find anyone else save for 100+ pieces bulk. Was hoping someone had an alternate source for them. Thanks in advance.

Trying to put together a good match for my HLG-185-48a driver and they seemed to be the best fit, though suggestions for other comparable strips would be appreciated as well.
