I've noticed that a few forums are using the default incandescent lamp icon, so here's some icons I did roughly in the same style, to fill the gaps.

They're already 60x60. Feel free to use them if you like them. And if someone wants to edit/etc. them here's the .SVG file containing all of them.

To add to your post/icons, I have about 4GB worth of stock icons/mock-ups from some package I purchased years ago. If you would like them let me know and I will setup a download link. Here is a screenshot of what I have.

these are great thanks! i'll go ahead and add them to the site once i get through this performance stuff i'm working through this week!

added to the forums thanks again!

my goal is to eventually either commission someone for a bunch of funky thread icons (ones unique and not just re-using the forum ones), or source them from the community. But i don't feel great about asking posters because i'd like to make sure the artist gets paid for their work

Thank you!

I did those icons for my own enjoyment, but I understand your view (to make sure that artists get paid). Plus I feel contributing with the community with those.
