Some time to work this light very well. But alas, you have to replace the light source (lamp). After repeated insertion ratstet think of nothing more, the luminous means base is worn out, the lamp no longer holds! This can also happen quite suddenly during operation, if only gently abuts against the lamp or changes the gooseneck in place. I have several G9 manufacturers from cheap to expensive tried: Always the same! An impossible design flaw. For the price you should be able demand a better quality.
