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:
“Nothing is so insufferable to man as to be completely at rest, without passions, without business, without diversion, without study. He then feels his nothingness, his forlornness, his insufficiency, his dependence, his weakness, his emptiness. There will immediately rise from the depth of his heart weariness, gloom, sadness, fretfulness, vexation, despair.”
—Blaise Pascal (1623–1662)
“Who in the same given time can produce more than others has vigor; who can produce more and better, has talents; who can produce what none else can, has genius.”
—Johann Kaspar Lavater (1741–1801)
