[1.9] Updating a blocks lighting

I have a block that changes light values depending on data from a tileentity. The problem is I can't find a function that updates the block's lighting. I have tried all of the following functions but none of these update the lighting in the world.

worldObj.markBlockRangeForRenderUpdate(pos, pos);

worldObj.checkLight(pos.up());

worldObj.checkLight(pos);

worldObj.scheduleUpdate(pos, Main.blockFurnace, 0);

worldObj.scheduleBlockUpdate(pos, Main.blockFurnace, 0, 0);

worldObj.markAndNotifyBlock(pos, worldObj.getChunkFromBlockCoords(pos), worldObj.getBlockState(pos), worldObj.getBlockState(pos), 7);

worldObj.notifyLightSet(pos);

worldObj.getBlockLightOpacity(pos);

worldObj.markBlocksDirtyVertical(pos.getX(), pos.getZ(), pos.getX(), pos.getZ());
