    The only way one can get the many thousand hour life from a CFL is to 
mount them base down. When the base is up the heat from the bulb rises into 
the power supply in the base and is what kills them.  Unfortunately, few 
ceiling fixtures allow one to mount the bulb base down or have sufficient 
ventilation for the base to cool in any configuration.

    On the other hand, I have table lamps with CFL' s with the base down 
that have lasted several years.

    YMMV.
