Elevator installation requires to be compliant with ASME A17.1 - Safety Code for Elevators and Escalators. Section 18.104.22.168 Location of Equipment in Machine Rooms, Sub-paragraph (c) of this code requires that, “Elevator Machine Rooms shall be lit by permanently installed electric lighting with a lighting intensity of at least 200 lx (19 fc) at the floor level”.
This code required lighting intensity of 200 lx (19 fc) is what the inspector is measuring, with the light meter during the inspection. The inspector does not care, what type of light source is used, although incandescent lights should not be used, because that will not comply with the current energy code. Both fluorescent and LED lights are acceptable. To comply with this requirement, you may do a lighting design intensity calculation before the installation, to determine how many light fixtures are required. Also, take actual lighting intensity measurement after the installation, with a light meter to confirm that the 200 lx (19 fc) requirements are met, before calling in the inspector. The machine room and pit lighting, also required to be with guards.
