It's fast and slow. I don't keep the part numbers in my head, but
you can tell them apart anyway: The fast ones have a silver collar
below the bus bar terminal, the slow ones have a brass collar.

Fast plugs warm up in 10-15s, the slow takes 2-3x as long. Mixing
fast and slow is not as catastrophic as people sometimes say.
Yes, they will break quicker, but not immediately, so if you
don't have the right replacement one or two of the other kind will
get you home. The fast plugs draw about 10A, the slows 7-8A. You
probably don't want to put all fast plugs on a slow relay and wiring
though!

No need to replace working glows. See my WWW page for several ways
of testing them.
