Light from torches

If my base has no windows and no cracks in it and I place a torch in it so I can see in the dark, why then does it then light up like a blooming Christmas tree so everyone with a set of eyes can see my base in the distance. Being on a pvp server makes it worse as I’m trying to keep my base hidden.

So suggestion would be to remove the light pollution from torches if your base doesn’t have any holes for the light to escape through
