Ok but pkoi such asymmetry?

I would rather have seen something like 40 / 20 second no?

asymmetry? ..... uh, it's not wrong

Ben on a tube lit in an "electromechanical" way the heating time does not exceed 6 seconds (on fluorescent bulbs
)
By the way, the cold starts are in my opinion one of the main vector of failure, so avoid a rise in temperature too much that would require to return to room temperature much more time thus causing a duration of tests at less tripled see even more.

At 40 / 20 I'm afraid that the bulb will heat up and cool down before the next ignition.

On the electronic part same thing, it is the off the problem and it must allow time for the capacitor to empty (54 seconds is in my opinion more than enough.

In short this choice is a compromise (thing due), to each tester (er, to by chistophe and me, there are others?) of
define its test conditions (different conditions = wider test range).

it only remains to add a pulse counter

to total the number of ignitions

Yes but a "stupid" calculation of the duration could be enough ... just to have an idea .... By checking 2 to 3 times a day that should be enough, right? (the goal is not to redo an ISO certification of bulbs)

In addition, I intend to do the test with a dozen bulbs simultaneously ...

The ideal would therefore be rather to think about a sensor of "death" of the bulb ... apart from the photo cell placed just in front of each bulb or a pulse sensor on the current of each bulb ... I do not see not sure what to use ... an energy meter graph can be? Seismograph style ... oh yes that would be great class

Tooout to Christophe

Beware of the adverse effects of the ignition of several bulbs with the same inter, much less sensitive, the fluos still seems to suffer.

Hey yes, I'm looking for, I'm looking for ........

I announce the death of 5W fluocompact bulb around 17h30

Result roughly 2900 on off for a given lifetime of 6000 hours, 1 all 2 hours except that the bulb had already undergone the test of 600 off on 1hour.
but good too frequent lighting still deadly

The autopsy of the bulb will take place tomorrow (if I have time) to define what to loose. (assembly or heating filament)

An 11 Watts has just taken its place at 19h15

Sincere condolences

Ha it's nice , but hey the light bulbs, one of lost ........

The cause of death of the 5W fluo bulb:
Slamming of one of the two heating filaments.
The electronic assembly has been rigged successfully on a fluorescent turtle

Ok, she was new before the pretest?

Try to write down the maximum amount of information on all the tests.

So how long did she shoot "in all" (with the pretest)?
