The tubes with a starting connection typically are also only available in T12 or larger sizes, and are pretty much not made any more these days. Never seen a T8 or smaller with a starting strip. In the examples shown one is a regular bipin tube, T12 with the end cap designed to be a contact in the holder and grounded, connecting the tube strip to the chassis ground deliberately.
The other is a single pin designed for a similar use, as it typically was used in EEX rated fixtures, which had a limit on allowed open circuit voltage so that the starting strip was required to get a high enough voltage gradient to start the tube with an open circuit voltage of 400V in the ballast. The long pins are designed as well to allow the tube connector to be part of the safety system, with them closing a contact to allow ballast power only when fully inserted, and if broken disconnecting power to the ballast. The cover is also part of the safety system, as it has interlocks that disconnect line and neutral power connections at the cable entry when you start to undo and remove the power, so that you can change the tubes even energised, with a lower risk of explosion from arcing, and the interlocks also protect if the cover is broken along with the tubes, as the broken tube means the ends are ejected and the power disconnected with the switch contacts still enclosed so any arc is contained in the connector.
