I am working on making a lamp running on gas, I got 1 for it being inactive that has no light level, and I got 1 for when it is on with light level.

 

But when it renders I get no light spreading, I have checked it so it says "Light level 15"

Hi

 

Are you sure you're placing BlocksAS.deviceGasLampactive in the world, and are you sure that you created deviceGasLampactive with true in the constructor?

 

I'd suggest you comment out all that switching logic first off and just try to create a block with light level 15.  If that doesn't work, there's a bigger problem somewhere

 

BTW delete this -

private static final String __OBFID = "CL_00000325";

it is used by the (de)obfuscation process for vanilla blocks only and will cause you problems if you include it in your own classes.
