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:
“In man, the shedding of blood is always associated with injury, disease, or death. Only the female half of humanity was seen to have the magical ability to bleed profusely and still rise phoenix-like each month from the gore.”
—Estelle R. Ramey (b. 1917)
“It would seem that man was born a slave, and that slavery is his natural condition. At the same time nothing on earth can stop man from feeling himself born for liberty. Never, whatever may happen, can he accept servitude; for he is a thinking creature.”
—Simone Weil (1909–1943)
