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:
“Nor could I rise with you,
Because your face
Would put out Jesus’,”
—Emily Dickinson (1830–1886)
“I have spent so long erecting partitions around the part of me that writes—learning how to close the door on it when ordinary life intervenes, how to close the door on ordinary life when it’s time to start writing again—that I’m not sure I could fit the two parts of me back together now.”
—Anne Tyler (b. 1941)
