Got a ballast or bulb and dont know what it is let stealthy's guide illuminate you 
Came across this info while trying to find info on my ballast thought itd be usefull.
Lamp Description Code:
Your lamp has an imprinted code that identifies the important features you need to select a replacement. A complete explanation appears below.
Lamp Description Example:
