Not good dimmable, to remain at ausgedrehtem Dimmer

So anticipate some theory: LED bulbs are generally not as good as dimmable bulbs. While incandescent less bright shine automatically with less power and thereby also a shift in the color of light takes place in the reddish, which is in the living area usually desired, the dimming pulse must be "translated" from the integrated power supply for LED lamps. The light color is in this case (so far) is not changed, the brightness can be reduced in two ways: either by reducing the current, or by pulse width modulation (PWM). Unfortunately, many manufacturers to PWM, which I do not understand is (I ask for an explanation in the comments The only conceivable advantage is the linearity.?) The disadvantages of PWM are: accepts it can not be dimmed to 0 down cleanly, and at low frequency you perceive, as it is known as a flicker of LED taillights of automobiles.

For lamp:
- The lamp flickers when it is extremely dim. That does not bother anyone but me immensely. When fast movements leading to a very unpleasant strobing.
- The residual brightness with dimming is too high
- The lamp lights when the dimmer is actually switched off. This could have one (it must not be at the dimmer, but it is up to the Lampem prevent this), if interested, can google it. Remedied by the way, the parallel connection of a light bulb, which is not simply out of the question.

My lamps go back and be "Osram LED lamp Superstar Classic A60 10W (equivalent to 60W) (827) E27 Extra warmton in Glühlampenform dimmable matt" replaced. I will report whether these "dimmable" are.
