The light color, gradation and intensity are adjusted in this LED control unit.
The time control is carried out via an optional, possibly already existing timer.
The controller supports 3 operating modes:
- White light for focusing
- Multigrade for exposure in the gradation range 00 to 5
- Red light for setting or placing dodging movements
The intensity of the light source can be dimmed in the range from 0 to -4 f-stops.
All values are displayed on a large, red LCD display and can be reproducibly adjusted using rotary knobs with detents.
A carefully stabilized 24V power supply prevents LED intensity fluctuations when the mains voltage changes.
Fixed gradation paper can be exposed in white light mode.
