[AT] LED lights

I had replaced almost all of ourold light bulbs with CFL's and I happen to 
be in the bathroom when I saw sparks come flying out of the light fixture. 
Scared the crap out of me (bathroom seems like a good place to be when that 
happens).  I did some research and the CFL manufacturers say that is "normal 
behavior".  Sparks?  Normal?   I did a search for "CFL fires" on You Tube. 
After than, I removed every CFL and replaced them with standard or LED's.

I have replaced my most often used incandescent bulbs with CFL bulbs and
as they expire I'll move to LED bulbs for those applications. With heavy
use the reduced energy cost recovers the bulb cost differential more
quickly. On the other hand those incandescent bulbs that I rarely turn
on like the ones in the attic would never makes sense to replace in the
same manner.

Maybe I can "leapfrog" the technology.
