I have used one of these and it failed in around an years time, though the company replaced the motor.

I wonder if we will get a "use and throw" type of fan now onwards. I am sure the fans using BLDC motors can be engineered to last a 100 years with attention to good design. But the profit motive will over rule all this.

Thanks Srinidhi.

Here is another sample (below) I found on the Internet to compare - Seems like the failure rate of F50 is very high on the above Bajaj bulb. And after doing a bit of reading, it is still not possible to make out if one bulb is better than the other for a lay person without understanding all the parameters thoroughly. And some of the claims of 25000 hours are not very clear (and what does 70% of the light compared to the original look like? One cannot judge that without a side by side demo). And below it says 15 years - that might be at 5% of the light output as LED bulbs do not always fail completely.
