how to set light levels automacily when placed

the game dose this on its own but how do I tell it to set the light level to something I want?

 

it's a bit odd; just make sure that changing the colour is the last thing you do, it seems to remember if you always do this last. So if you want to make a change to light level, change the level and then change the colour (change it back again if you want it to stay the same colour).

hope that makes sense!

 

that's awesome thanks
