Then, suddenly, nothing.
Ah, these are the batteries are flat, replace them. It works
Unfortunately nothing without the use of the lamp, when tested after 2 hours. A new flat batteries ...
Test with rechargeable batteries (If it fair, is recharged. Cheaper), same thing.
New purchase of the same material, mixture of parts.
Diagnosis: this is the old container of 3 batteries which became fair game! We should be able to acquire this piece separately.
HOPE: that this new lamp takes the shot.
