A lot of commercial lighting is switching off of HPS because of claims about LED lifetime costs based on (seemingly false) figures about durability. (E.g. drive around Los Angeles and see the dead/dying LED streetlights all over the place).

I wouldn't be surprised if HPS lightning starts becoming unavailable as a result-- this has already happened with LPS lightning, with several manufacturers shutting down fabrication.

LED can be made durable if desired. In Detroit's case[1], the high failure rate can be attributed to manufacturer cutting corner on heat dissipation.
