The instructions given by LUX weren't very helpful, so I was able to find this Chinese DIY on how to install these bulbs. It has tons of pictures, and should be pretty self explanatory even if you don't understand the text (just use google translate ifs really necessary).
Anyways, here it is, hope it helps others who bought these.
