Trend seems to have started with these Bell+Howell "Triburst" things with three flaps, 4000 lumens. They're up to four and five flaps, have seen one at 8000 lumens...a bit crazy.These are usually marketed as garage lights due to many a new build garage lacking fixtures beyond a ceiling-mounted duplex outlet (for a garage door opener) and perhaps an Edison socket. The 'deformable' feature allows for crude distribution control from the latter as well as some potential to fit the former.
