    No, bulbs flicker because the power coming to your house has a dip for a second or micro second. It is called a "brown out".

    If you are worried about your PC getting damage buy a Uninterruptible Power Supply. Get a sine wave one if you get one. Also get the right one for your PSU and load.

    Is this possible that bulb is near death? On other forums told me that bulb can be in near end.

    Yes, especially if it keeps on flickering. It is possible.

    If it happened once yesterday and has been fine since then, then it's probably not the bulb, just a dip in the power coming to your home as Calliers said. I would expect that It was not the only light in the house that flickered.

    Then yes it is probably just the bulb that is about to die, most probably. Especially if it continues to flicker after that, those newer bulbs tend to flicker near death.

    It happened when i close door in my room

    Since it happened as you closed the door, I suspect it was not tightly screwed into the socket. Try making sure it's securely twisted into the socket.

    If it has filaments, it's possible that there's a slight break in the filament...which could be an indication that the bulb is about to go dark permanently.

    That is a early day energy saver Florescent Bulb... They do have a lifespan the same as most bulbs.

    In the UK Halogen Bulbs are going to be no longer Sold in the UK in Sept of this year. Followed By Florescent bulbs with in the following year and i think that will include that type of bulb.. Then we can only Buy LED Bulbs that have a much lower power consumption and a much Longer life span.

    I don't know if that is the same were you are, But I have used those types of bulbs a long time ago. Most of them started Flickering within two years. and shortly after they just refuse to work... I no longer use those, and i now only use LED Bulbs.

    I would say the bulb is close to the end of its life.

    The interesting thing about these kinds of lights is that they can flicker for like, ever, before they finally die.
