Compact Fluoro's - operating position?

Re: Compact Fluoro's - operating position?

No, you are thinking about incandescents, these should be installed
base up
CFL should be installed base down where possible, though In my
experience,
I have had no noticeable trouble using 18w and less CFL's base up in
normal
household light fittings that were originally used with incandescent
bulbs.
Some of the larger ones - (such as those 60w ones Bunnings had a while
back)
may be a problem due to the greater heat involved, but have not tried
them.

"who where"

** Now you tell us .....
What failure symptom is linked to this alleged mercury V gravity issue ??
All the CFLs I see fail because the filaments go open, the electronics fail
or the glass breaks - none last long enough for the light output to
diminish much.
AFAIK, mercury is absorbed into the white phosphor and turns to vapour soon
as the tube heats up - there is always enough vapour at room temp for the
lamp to light up OK - but not so if the CFL is very cold.
Try this:
Put a CFL in the freezer for 10 minutes and then plug it in and see how dim
it is.
