Every efficient modern tungsten/HMI light has both a parabolic reflector and a fresnel lens, even down to 2" elements. The two definitely work great in conjunction.

But I won't argue that designing a purpose built fresnel is hard. There's big dollars in good fixture design.

I have a pile of old, stripped Mole-Richardson and Arri Fresnels at work, and I've always wanted to convert one to 12VDC to run as a head light just for shits and giggles.

One with wide beam and one focused to narrow beam.
