To be more specific about my main high failure rate application, I have
a ceiling fixture over the bar in the kitchen. It is separated from the
sink and stove by ceiling mounted cabinets. There are 4 horizontally
mounted 100W equivalent CFL's. It is turned off and on several times a
day but no short cycle use. I have gotten into the habit of marking the
date on a bulb when I install it. Approximately 6months is about as
long as a bulb will last.
I buy bulbs at Home Depot or Wal-Mart and get whatever is on sale or the
cheapest so the brand will vary. I don't buy Philips because they
seem to be priced about double that of any others.
I see a definite difference in life between the straight tube and twist
tube CF L's. The straight tube seem to last much longer to the point
where I have no complaint about their length of service. I have a
couple of those that I have had for years.
There have been some comments about the Lights of America brand. All,
only 4, of the straight tube CFL's I have are Lights of America. I know
I haven't bought one of those in over 10 years.
Three way bulbs have given me unusually poor service life but
incandescent bulbs do the same. I don't know what it is about three way
bulbs. I have not tried the dimmable CFL's.
