GE Manufactured tubes ... a Saturday morning puzzler.

12.238.236.61

I have a number of GE made tubes and all of them have a series of small dots printed on the side of the tube. In some there are as many as three rows and four or five columns of dots, but not all the possible positions in the matrix contain a dot. In other examples there may only be one row of dots. First question, does the arrangement of these dots mean anything? Second question, if yes to the first, what do they mean and how does one interpret the code?
