Incandescent Bulbs Blowing Frequently: Why ?

Hi

Great Forum and folks.

Have the conventional overhead 2 socket light fixture in kitchen.

For the last month or so, incandescent bulbs (75 W) seem to last only about
a week ! Works fine for that period.

Is this due most likely to the quality these days being so absolutely poor ?
What might be other reasons. ?

The only thing I can think of for blowing an incandescent bulb is over voltage, and
that cannot be the case here.
Even if the fixture is bad, or going bad, I cannot see how that would blow the bulbs so frequently. True ?

Any thoughts ?

Thanks,
Bob

Incandescent bulbs are not manufactured to the same high standards they used to be.
Many incandescent bulbs have been or are being phased out soon.

Most fixtures are labeled for 2x60w bulbs as anything higher creates too much heat.
Have you considered using LED bulbs.
A "75 watt" LED requires approx 13 watts of power. Two of those in a fixture would be fine.
Much less heat inside the fixture.

Are you able to check the voltage at the light? Sometimes bulbs will have short lives if the voltage is off from nominal. Additionally, while I don't suspect this here, they don't tolerate movement well, if the fixture is shaken or disturbed - this is why garage door openers typically use heavy duty bulbs.

That said, I agree with Pete on switching to LED.

Have all the bulbs been the same brand purchased at the same time? Along with the quality declining, if you get a bad batch, it's quite possible all the bulbs in a box or manufacturing batch can have shorter than expected lifespans.
