I've a couple of small and neat, well-made German 300w lamps I don't use. I've only used 60w bulbs in them as back lights. They seem to get hot with 300w bulbs. I have plenty of bulbs, dichroics and the lamps have safety glass in them, barn doors, flood and spot, one stand, camera mounts and handles etc.
Maybe too late but is this of any use? Around £75
Unomat LX500 GS - new unused boxed
1000 watt mains operated halogen video light.
Zoom flood to spot
Tilting hand grip
I've been using 85watt ( 500watt ) fluorescent bulbs,Daylight balanced at 5800. just replace the modelling bulbs in studio flash heads, and can the use existing reflectors etc.Run very cool. I found using two bulbs in studio ample. This my latest effort using that set up. https://www.youtube.com/watch?v=i45Flxl0jgU
