PL-T and T Dulux lamp bases

The lamp bases are made so that the bulbs are not interchangeable. The version with 2 pins for conventional gear (2pin) and the version with 4 pins for electronic gear (4-pin)! The version with two pins has an internal starter in the lamp cap and the electronic is not.

These can not be exchanged because the pin 2 has a built-in starter and the 4 pin no. This is ignited by the electronic ballasts. One can look at the fixture how the fitting looks.
