If someone insisted that I make such a device (OP), I would maybe do the following:
Design and make a custom bench power supply, with a maximum voltage output rating to suit the desired maximum working voltage of your bulbs, and give it an adjustable voltage control knob.
Connect the bulb under test, to the power supplies output. Then the program (if it has an MCU) inside the custom bench power supply, can calculate the resistance across its output, and hence calculate and display both the set voltage and resistance in Ohms.
Maybe call it the "LazyOhm" range of power supplies.
