There are relative power values. When both lamps (regardless of the type*
and its power)
have the same value displayed, energy are also the same.
Status of the readiness is indicated on display too. When the lamp is not ready to use (is
charging or discharging) set value on display blinks until loading process is complete. When
the lamp is ready display shines constantly. Display functioning like this is regardless of
acoustic signalling and occurs in any situation.

Encoder
Digital potentiometer in other words. It is used for energy and level of modelling light
to be set. Construction of energy control knob is based on potentiometer with unlimited
revolution angle. When it rotates, displayed values are changing instantly. Energy value is
shown with 1/10 f stop accuracy.
In order to increase the energy twist the knob right (clockwise), to decrease, twist left
(counterclockwise). As a result of changing energy, lamp has to charge up itself, or (if
decreased) dump excess of energy gathered inside capacitors. Display is pulsating when it is
being processed. Display shines continuously when it is finished and lamp is ready to flash.
