Four dimming modes are available:
LINEAR The increase in light intensity appears to be linear as DMX value is
increased.
SQUARE LAW light intensity control is finer at low levels and coarser at high levels.
INV SQ LAW (Inverse square law) light intensity control is coarser at low levels and finer
at high levels.
S-CURVE light intensity control is finer at low levels and high levels and coarser at
medium levels.

1200 Hz.

Cooling Mode
This option sets whether cooling fan speed is regulated depending on fixture temperature or
whether the cooling fans run at a constant speed.


REGULATED FANS
– Fan speed is controlled by fixture temperature. Fans only run at the
speed necessary to keep the fixture within its normal operating temperature range. Light
output is not reduced unless full fan speed is not enough to keep the fixture within its safe
operating temperature range.

FULL
– Fans are set to constant full speed. Light output is not reduced unless full fan speed is
not enough to keep the fixture within its safe operating temperature range.

LOW
– Fans are set to constant low speed. The maximum light output available is reduced by
approx. 15% and fan noise is significantly reduced.
