[LVL ED] billboard and boxlight question

[heyitsrobert97]

Hi, I Need To Know How To Make A Billboard lightray look very dull. at the moment it is a pale yellow and forms a circle every 15y rotation but it is so bright in game that you can't even look at the screen its so bright. how can i dim it right down.

and with a boxlight is it possible to make it light a room a little bit rather than it being like the brightness setting of the game is at max.
