A line voltage halogen lamp is an incandescent lamp with generally twice the life, a higher color temperature, and a smaller size so they are preferred for track lighting. Fluorescent track lights are larger, there are fewer choices, and the light is more diffuse. Of course, low voltage will throw much more light so is usually preferred for task and accent lighting which is the usual purpose of track lighting. You should try to find a way to avoid putting fluorescent lamps in fixtures designed for incandescent lamps.

Go to any manufacturer's website and look for line voltage track lighting fixtures for either incandescent or fluorescent lamps.
