    I am looking for a bulb with a built in photo sensor. The separate light sensors when added to the bulb make it too tall for the fixture

    Get a shorter bulb!

    They're made in many different sizes, you know.

    And what should be the use of it? To check if the lamp is working? Or to use the sensor as a night/day sensosr?

    It's to automatically turn on the lamp when it's dark out, and turn it off when it gets light.

    Our OP just needs to find a shorter bulb. There is a terrific variety of lamps available, but one needs to look further than the housewares section of a grocery store, where the selection is slim pickings. The OP may need to look at a specialty bulb supplier.

    The sensor is going to have to have some separation from the bulb, or it will never turn off.

    Yes but i don't think he has answer the question. Maybe is a way to test if lamp is ok. Making a dark activated switch this way is a little bit not corect because the sensor should be attached somewhere else and not on lamp...
