It's hard to understand why some have so much trouble with CFL's. I've done CFL conversions in at least 5 houses in three states (including relatives and in-laws) without any problems. I mount them up, down, enclosed, all-around.
One set worked really well in an old 1930's wired house that couldn't get enough juice to the bathroom to run anything but the CFL's--they finally rewired it and replaced the box.
Recylcing is easy, no need to sort, just take them to HD when you make a trip.
