Rise Time
One measure of the quality of the dimmer is the "rise time". The rise time in this context is the amount of time it takes within the cut part of the waveform to get from the zero-point crossover to the start of the uncut part of the waveform. A longer rise time reduces the noise of the dimmer and the lamp as well as extending the life of the lamp. Unsurprisingly, a longer rise time is more expensive to implement than a short one, this is because the size of choke has to be increased. Newer dimming methods can help minimize such problems.

Famous quotes containing the words rise and/or time:
“... the French know that you must not succeed you must rise from the ashes and how could you rise from the ashes if there were no ashes, but the Germans never think of ashes and so when there are ashes there is no rising, not at all and every day and in every way this is clearer and clearer.”
—Gertrude Stein (1874–1946)
“The world was not created once and for all time for each of us individually. There are added to it in the course of our life things of which we have never had any suspicion.”
—Marcel Proust (1871–1922)
