@Golden Thanks! So that’s not just me. What browser are you using? Is it Firefox?
Seems like it’s either Discourse problem or FF rendering HTML tags incorrectly 
However the preview showing correctly strongly suggests it’s Discourse. Google suggested it was a known problem with older versions of Discourse but it supposedly got fixed in the latest builds.
Edit: The initial post now holds short descriptions of every light currently available on Github. With pictures! You can see the lights even before you install them! Weeeeee! 
I prioritise GH build updates over others.
