Lot of 4 Studio Spot 250 units, sold as-is. All four have various issues, and display different error codes, however they do all power on. It may be possible to salvage parts from these for another unit, or combine parts from them to get at least one to work. We do not know any details as to what each error code means; you'll need to have a working knowledge of these lights and be able to diagnose and repair them yourself. Each unit has been labeled with notes on which errors the unit displayed(see photos). None of the units contain bulbs, so you will need to source those as well to properly test.
