DIMMER Light intensity variation
The dimmer of the VDC Control Unit is totally digital and guarantees the regulation of light intensity
with minimal changes in the selected colour temperature.
Light intensity can be easily increased or reduced through the +/- buttons located at the VDC
Control Unit front panel. Above them a digital display indicates at all times the selected dimmer value
from a minimum of 1 to a maximum of 9.
Push the + button to increase light intensity or push the – button to decrease it. If you keep pushed
any of the buttons the you will get a continuous variation.
NOTE:
Every push on the buttons will increase or decrease the light intensity in calibrated
increments of ! stop.
-/+ GREEN Green/magenta bias control
Green/magenta bias switch located at the VDC Control Unit front panel lets you easily alter the
colour of the light emittting at any colour temperature towards green or magenta in increments of -
/+ 1/8 and ".
When this switch is not in the standard position a green LED light turns on in the VDC Control Unit to
warn that the light emitted no longer guarantees the correct chromaticity.
NOTE:
THELIGHT guarantees the correct colorimetry for light emitting from their high power
LED light fixtures, calibrated in the laboratory according to current international
standards of the CIE 13.3-1995 for the average CRI and the chromatic co-ordinates (x, y
CIE-1931). This certifies that our luminaries have no green/magenta deviation.
NOTE:
Full adjustment is possible in a range of colour temperatures from 3900K to 5800K.
From 2800K to 3900K and from 5800K to 8500K the adjustment is possible only on
1/8 and " plusgreen.
