BAD power factor?? [RE-wrenches]

[sunwise]

I agree with you Jeff about cheap CFLs from China, especially on
Mod-square wave.  Regards to power factor, I wondering if something else
is happening here.  

You can't use the ratings on the label to figure out how much power the
light bulb or any appliance uses.  They are almost always listed high or
at the highest surge in the worst conditions.  For instance, while a
typical, medium sized TV may say 200 watts on the label, it will
probably operate closer to 60 - 80 watts in normal operation.

"Wrenches what's up with the wattage rating on the CF lamps these
days? I
have different lamps from two separate manufacturers. These are "made
in
China" lamps purchased at Cost-Co R."

I don't know why unless difference in testing procedures, but my very
un-scientific market testing has shown that all brands labeled "made
in China" have had much much shorter lamp life than the Oshram brand
we have been using for years.

Not bashing China, just our experience.  We have replaced many Oshram
CF that lasted over 8 years of everyday use, then had multiple
failures within first year using these China replacements.
