Few people think about it, but an ordinary incandescent light bulb has given every modern person an extra 6 years of active life.
Before its invention, people slept on average 10 hours a day, after - only 7.5 hours.
Many of you have probably heard the story about the light bulb in the fire department of Livermore (California, USA), which has been shining there continuously since 1901.
There is even an online broadcast of this process on the Internet - THOUSAND. To date, the light bulb has worked continuously for more than 1 million hours!
A natural question arises: why don’t the light bulbs in our homes shine for so long?
For some, they burn out literally within a few weeks or even days after replacement. And there are two explanations - technical and conspiracy.
Moreover, both have the right to exist. Let's look at both in turn, and you, having already made the appropriate conclusions, can take the necessary actions and try to fix the problem.
Reason #1 - Tension
If you have light bulbs constantly burning in different rooms, and not specifically in any one chandelier or lamp, high voltage in the house is most likely to blame.
If there is a burnout in one particular place, the reason is completely different. Let's look at it below.
Check the voltage in the outlets with a voltmeter. According to the new existing standard, it should be 230V (not 220V!).
Reference to the standard - GOST 29322-2014
Moreover, from time to time it can differ both down and up by 5-10%.
Light bulbs always indicate the maximum limit for which they are designed. At the same time, light bulbs are different!
Believe me, your outlet could easily have a voltage of 250V or even a little more.
Especially if you live near a transformer substation (TP, KTP) or on the first floors of a multi-story high-rise building. At the same time, all other equipment will work perfectly at these values.
Titanium heats up faster and the grill cooks steak faster.
First of all, it is the light bulbs that react to this, as the weakest link.
An increase in voltage of just 3% can reduce the life of a light bulb by a third!
By the way, few people mention it, but the same “eternal” lamp in the fire department is supplied with a voltage of only a few percent of the nominal voltage, only sufficient for it to barely shine.
If you apply such voltage to your chandelier, then it can easily turn into “eternal” and work for a hundred years
