LED bulbs need a lot of air circulation to remove heat. Ceiling fans tend to house the bulbs inside smallish glass globes trapping the heat which reduces LED & electronics (driver) life.
My Philips 7W under WARNINGS AND CAUTIONS specifically states "Suitable for use in open luminaries,
not for use in enclosed fixtures".
LED bulbs may not be the best for this application. I guess you can always run without the glass globe but then it would look ugly.
I'm looking for a good E27 regular 110vac socket warm LED bulb, I have bought the stuff from China and it only last about 3 or 4 months.
I want to use these LED bulbs in a ceiling fan in a kitchen
If you look at
Guiri's ceiling fan you can see PAR type bulbs are not suitable.
Maybe a suggestion for a globe style bulb would be better.
Here is an example of one of our customers using our LED PAR20 warm white in his kitchen:

I just posted this in the best MR16 thread. You can take a look at the post for more information.
C. Crane and LEDwaves are the only mail order companies I know where all the bulbs are
UL listed (or equivalent). For other companies only some or none of the bulbs are listed. EarthLED for example only the Evolux, Zetalux and their dimmable bulbs are listed.
The bulbs from big name companies like Philips and GE are listed.
If an electrical appliance including light bulbs that are run off the mains failed a household fuze would not blow until some 2000 watts is reached. That is more than enough to start a fire. So always use listed equipment when powered off the mains. The safety labs I know that tests and lists electrical equipment are UL, CSA, ETL, MET, FM.
