Older Halcyon Scout with 2 LED conversion modules. Just need to get an aluminum spacer for it, which you can find at any Home Depot or Lowe's. Comes with boltsnap on the back. $65 shipped to CONUS
Halcyon 10W HID in great condition. Comes with charger, battery (more than enough for a 2 rec. dive day but I didn't test it beyond that--likely has many hours), handle, and a 3rd party foam-lined hard case. It's a great light as-is. When the bulb dies you can convert it to a killer LED can light. $100 shipped to CONUS
