How to extend the life of an incandescent lamp using a diode?

Sergei asks:
Interested in the topic of extending the life of incandescent bulbs with a diode. Indicate the brand of each diode, which for this purpose is screwed into the network break, - for a bulb of 100 watts, 150 watts, 200 watts. Can a capacitor help in this case?
The answer to the question:
Hello! You can use any diode with a reverse voltage of 300 (undesirable), preferably 350 volts and above, but with such a low voltage, mainly domestic ones go, if of them, KD202 with the letters M, N, P, C at the end, KD226V, G will do , D, D245, D248 and others (see the reference books for parameters). If from abroad, it is somewhat simpler here, you can use 1n4007, 1n5399, the direct current diode should be at least 1A. In general, it depends on the lamp power in order to determine the lamp current - divide its power by 220V. The capacitor is needed relatively large, for non-polar capacitors, capacitance, and will take up a lot of space. It is simpler and more convenient to use a diode.
