They are nice.  VERY white.  As far as colour goes, the big advantage is that
they don't go orangey on you with a dimmer.  They are also considerably
smaller than their incandescent counterparts (as floods that is).  The 
difficulty with them in pot lamps is that since they're smaller, they are
more recessed into the fixture, and the fixture tends to narrow the flood.

H'm, my 50W floods get pretty darn hot.  Not as hot as bare QH, but
can still do some damage.

I bought 9 of them at a good electrical supplier (who's prices are
usually very good) and got a discount.  Only $12.50 apiece.  (Only
in Canada eh?).  QH floods are more typically $17+.

I ran the 9 for about 6 months before we sold the house (and salvaged
the bulbs!  At $12.50 apiece you think of these things!).  One died
fairly early (a mechanical defect actually), the others were fine.
We'll be reinstalling them here outdoors probably.
