Font weight for the weather icons

[obones]

Hello,

I've been using the weather icons from Erik Flowers and as has been mentioned in the discussion you stepped up to work on them as they are discontinued in the original repository.
I have two questions:

1. Which file should I download to get those icons? Is this NerdFontsSymbolOnly.zip?
2. Is there a way to generate them with a lighter weight? I believe the originals use a weight of 400 which is too much for my use case but I'm not too sure how to change that to 300 or 200.

Thanks a lot for your help here.
