Not quite understanding you test with another proper bulb.

The HPS bulbs are interchangeable. No circuit board. Most older HPS bulbs are designed to work on a mag ballast (low frequency). Using an older or low frequency HPS bulb in a digital ballast will work, but most likely fail prematurely. Metal Halide pulse and probe start is a different story.

Some but not all digital ballasts you can.
