Actually, >for a reasonable amount of light output<, compact fluorescents 
are almost always more efficient than white LEDs.  There are a few 
prototype 
white LEDs now that can match and possibly even exceed CF efficiency, but 
they're not available at a price that a normal mortal would want to pay.

OTOH, if all you want is very dim light, just enough to see by, white LEDs 
might be just the ticket.  The reason is that at very low wattages (1-2 W 
or 
less) fluorescent ballast loss becomes dominant.

Wow, this is getting off topic.  Sorry.
