Issue Description:

Conduit facades remember and emit light levels around them after the light level has changed(I think).

What happens:

I have a few conduit facades in and around my mob farm, when the electric lights/redstone lamps are turned and on off,
sometimes the conduit facades remember their previous light level and now emit light in my mob spawner.
Conduit facades also kind of let light through/have strange lighting property's.

What you expected to happen:

I expect the conduit facades to use the current light level around them and not create light in my mob spawner.

Steps to reproduce: #4577

I honestly have no clue how to produces this but can give a download to my server's world
I used some form of chiseled basalt as a facade.
