This is a nice 1k light made by Arri. It is tungsten halogen, and the quality of light is much better than any LED's being made today. I used Arri lights when I was at film school and I miss the look/functionality that they bring.
This one has a few condition issues. It is missing one of the clips to hold barn doors as well as the barn doors themselves. The reflector that moves for spot/flood is a bit loose, I can hear it moving slightly inside of the unit and the spot/ flood knob is also a bit rough feeling. Spot/flood does function but requires a little bit of work.
