I forgot about the fun we had at the time: it was enough to operate the ceiling of the button to be light, fast, and everywhere at once ...
In recent years, my wife and I have eaten a lot of low energy light bulbs at 8-12 euro coins. Some have floundered in the year (when it is not within six months), others systematically refused to give light before he is most in need (in the toilet, for example, or before bedtime), and most were burying us in an unpleasant yellowish veil.
As a bonus, while the old bulbs can be thrown in the garbage eyes closed, new demand to be picked with tweezers and throw them in the boxes provided for this purpose (because they contain full of quite toxic).
In short, the history of the incandescent bulb is a first in the history of mankind: all households had to replace an effective product with a product that was not and that cost ten times more. Think about it: this is exactly the opposite of what we call ... Progress!
5 MONTHS LATER:
Both bulbs I screwed in September (lounge and main passage) still hold up. Braves small!
