varying lamp current magnitude to adjust light output,
RangeMAX™ inverters use a fixed lamp current value with
a duty cycle control method.
100% (continuous lamp current) down to a 2% duty cycle,
allowing the lamp to be dimmed to less than 1% of its full
brightness.
careful 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
The lamp current burst width can be modulated from
