tom has left a new comment on your post "Philips CFL Bulbs only 1 Euro":
Why are the manufacturers and promoters of cfl bulbs claiming long life on these bulbs? Six years ago I started using these bulbs , I have had to replace many of them in that time , I now put the date of installation on each bulb.
Today I replaced 2 Philips genie 8w screw cap bulbs that I fitted on 11/4/09, 1 blew 2 weeks ago & the other blew yesterday.

Tom, I have some 22 CFL bulbs currently running in my house. Like you I started to put the date on the base of the bulb with a pencil, so I have a fairly good idea about the lifespan. All CFL bulbs have their lifetime quoted as an "average" number of HOURS. Frequent switching on and off will affect the lifespan, as will any form of dimmer.
Regarding Philips CFL bulbs specifically, about 4 years ago I experienced a high rate of failure in some Philips bulbs at that time. I contacted Philips and they were very good about it and sent me a bunch of free bulbs.
Now, only occasionally does one blow. My porch light is the most frequent one to blow. This light is switched on during the winter time from maybe 4pm till 9am the following morning. That adds up to 17 hours a day. That bulb lasts about 2 years on average. I am not dissatisfied with this lifespan, which averages out at about 9,000 hours. I would have replaced at least 4 filament bulbs in the same period.
You might have got a dud batch, in which case, you should contact Philips.
I still think CFL bulbs are terrific value for money and a really great energy saving method. As LED bulbs improve in design and reduce in price, they will eventually overtake CFLs, but that time has not yet arrived.
