~~Hey thank you for maintaining this. I really prefer the look of a overhead lamp instead of the floor lamp. It seems the API change in 2.1 has to do with recipe configuration. and so it seems like most other mods its been an easy fix.
I look forward to seeing if you are able to patch the lamp being always on, or allow us to change the colour of the light. ~~
EDIT: I updated the the lamp post to work on 2.1 let me know how I can give you the change.
