Are the tombstones shunted or not ? I am in the process of converting a retro high school. It contains 22 apartments, a nursing school and a senior day care/ health center. As long as both LED tubes are inserted exactly alike we never have an issue. Even if you disregard the "L"&"N" they will illuminate properly.
Of course I am posting of ballast bypass LEDs, no practical reason to do otherwise. It is 2018.
