Does anyone know the reasoning / sustainability behind not specifying circular fluorescent lamps? For LEED HC MR4.1 PBT Source Reduction - Mercury in Lamps, it says Do not specify them. Thanks!

My understanding is that these are considerably less efficient and less regulated than other higher use lamps, and as a result effectively have more mercury per lumen output. (That's the case for the US but not the EU.) I've also heard that they're harder to recycle, but don't know the details.
