Hi, I would just use IES lights. They should render reasonably fast. I am attaching an example. This is a simple scene and the setup was quick and dirty, but it doesn't look like there are any problems. The main goal is to avoid any kinds of mistakes that could increase noise - like lights intersecting with objects, lights shining directly at highly reflective objects (though I added reflectivity to all walls and floor to make it harder), too high albedo.
~15 min rendering, there is still some noise, but not much, and it would probably require better render settings.
The "filaments" in halogens have Corona mtl with self illumination. They would cause problems if they were lights, but self illumination gets clamped by MSI so there is virtually no problem with caustics. I think if you populated the scene with some high-poly models the render times would be still reasonable.
