There is quite a lot of different ways to do this, but one way that might work for you is to change the “Shape” of a point light by using the “Source Radius” and “Source Length” inside the point light “Light” properties. This will create a light shape similar to a strip light (Fluorescent tubes) if you enter values like 5 (or something similar) for “source radius” and 200 (or something similar) for “Source Length”.
I imagine there is more performance cost for this (but don’t know for sure), however but might be good for testing.
