(BOOST) and a brightness control (BRITE) for dimming.
Please see following sections for dimming and amplitude boost
control. To achieve extremely wide dimming ranges, rather
than only using the traditional dimming technique of varying
lamp current magnitude to adjust light output, RangeMAX
inverters utilize 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 2% of its full brightness
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.
