2. OVERVIEW OF LED SPOTLIGHTS
In comparison with conventional tungsten-halogen spotlights, Cetra has an LED solid-state electronic light source, which is
more energy efficient and longer lasting than a tungsten-halogen lamp. The implications of using an LED source are as
follows:
A 89W LED is ‘built-in’ to the spotlight, and when the time comes to replace it, this will require servicing via your local
dealer. The LED is not a plug-in replacement component and is not user-serviceable.
The colour temperature of the LED is fixed at either ‘warm’ 3200K theatre-standard, or ‘cool’ 5600K, which is becoming
more common in TV studio applications and in theatres using colour filters.
Although regular colour filters may be used with an LED source, the non-continuous spectrum of the LED produces a
different effect with many standard colours. Lee Filters, Rosco and other manufacturers supply colour filters specifically for
use with LED spotlights. These LED filters are generally matched to 5600K (cool) white sources. Please check you are using
the correct source/filter combination.
The spotlight requires a constant mains power supply (not a dimmed supply) and a DMX signal. The DMX signal is used to
control intensity and performance features of the spotlight. Refer to the operational section of this manual for details.
3. MECHANICAL OPERATION
The mounting stirrup
is designed to allow the spotlight to be suspended from above using a C-clamp or similar, or
supported on a stand or bracket from below.
Note:
the spotlight’s location must provide suitable ventilation for the LED
module.
Focus controls
is located on the rear end of the product. Turn the knob clockwise to narrow the beam (SPOT) . Turn the
knob anticlockwise to widen the beam (FLOOD) . The beam distribution (peak/flat) is fixed.
Beam-shaping
