lamp current magnitude to adjust light output, RangeMAX
inverters use a fixed lamp current value with a duty cycle control
method.
(continuous lamp current) down to a 2% duty cycle, allowing the
lamp to be dimmed to less than 1% of its full brightness.
design consideration was given to controlling lamp start voltage
to softly start current flow. This eliminates current overshoot that
can result in premature cathode wear and reduce lamp life.

Rather than using the traditional dimming technique of varying
The lamp current burst width can be modulated from 100%
