PREFACE
THE CANTO FOLLOW SPOTLIGHT is manufactured in Italy by Luci della Ribalta and
imported and marketed in the United States by Strong Entertainment Lighting. The metal halide Canto
models are available in 575, 700, and 1200 watt models, and require use of a separate power supply unit of
the correct wattage. Each power supply operates from a 120 volt, 15 ampere AC line. Tungsten-halogen
models, using either a 1000 watt FEL or 2000 watt GAE bulb, operate from a 120 volt AC line (20 ampere
service required for 2000 watt model). Each unit is supplied complete with a lamphouse, optical system,
yoke, and 1-1/8" (28mm) spigot/truss pin. The metal halide power supply is included as required. Atripod
floor stand and a five-color boomerang are available as optional accessories.
BULBS and color gels are available from theatrical supply distributors. Rated hours or
warranted life of the bulb will vary by type and wattage, and should be noted at installation. It is
generally recommended to keep a spare replacement bulb on hand. Bulbs from manufacturers other
than those listed on Page 5 must be certified by their manufacturer as being 100% interchangeable.
IMPORTANT SAFETY PRECAUTIONS
• This product operates at high temperatures. Avoid any direct contact with its metallic parts.
• WARNING: high voltage ignition cycle.
• UV Rays: the lamps used on the metal halide models (Canto 575, 700 and 1200) emit UV rays. Protect
your eyes and never look directly at the source of light without appropriate eye protection.
• This product requires forced-air ventilation. Make sure you do not cover the fan or obstruct the air
flow at any time.
• Make sure the fan is working correctly. Should you detect even the slightest malfunctioning, switch
the spotlight off and carry out the necessary servicing. Replace the fan if necessary.
• This product is designed for indoor use only. For details on maximum ambient temperature, minimum
distance from flammable objects, and tilt angle, please refer to the data plate.
• Replace the bulb, the mirror and the lenses if damaged or deformed by heat. Make sure the lamp is
cold before attempting to remove it. To correctly install the lamp, please refer to the lamp manufacturer’s
instructions included in the lamp box and to the relevant section in this manual.
• Repair and replacement of any component of this product must be carried out exclusively by trained
personnel in compliance with the relevant safety and health standards, and using only original factory

4. MOUNTING THE IRIS
The iris supplied with the followspot uses 20 leaves to size the beam from a maximum aperture of 2.68"
(68mm) to a minimum of 0.20" (5mm).A blackout iris is available on special order. The iris is preassembled
in Strong Entertainment Lighting units, and replacements are installed as follows:
a. Using a phillips screwdriver, remove the two cross-head screws from the sides of the iris bracket
located in the gap between the lamphouse and optical system. Lift the old iris out of the bracket.
b. Slide the new iris down into the bracket, flat surface toward the lamphouse.
c. Replace the screws.
Important Notice: while the lamp is on. . .
Do not leave the iris closed for longer than:
• 10 minutes on Canto 575, Canto 700, Canto 1000 and Canto 1200
• 2 minutes on Canto 2000
Use the douser (front lever) to cut off the light should you require to have the lamp “on” with no beam
projecting to the stage.
FAILURE TO COMPLY WITH ABOVE NOTICE MAY CAUSE THE IRIS AND THE FOLLOWSPOT
TO SUFFER MAJOR HEAT DAMAGES AND WILL INVALIDATE THE PRODUCT WARRANTY

b. Tilt the spotlight downward and locate the lampholder block in the bottom of the lamphouse. Open
the lampholder block by turning (counterclockwise) the two quarter-turn fasteners.
c. Pull the lampholder block down and insert the correct bulb in the lamp holder.
MAKE SURE THE LAMP IS CORRECTLY POSITIONED AND PERFECTLY VERTICAL

12. IGNITING THE FOLLOW SPOT
Tungsten-Halogen models:
a. Connect the followspot to the AC receptacle (fan will start running).
b. Press the main power switch at the back of the spotlight (lamp is on).
Metal Halide models:
a. Connect the follow spot to the power supply unit. Please note that each followspot has been factory-
tested with relevant PSU. Both units are recognized by a serial number (on the outer box and on the
unit). Make sure you match each followspot to the relevant PSU.
b. Connect the PSU to the AC receptacle.
c. Push the main switch on the PSU (fan will start running).
d. Push the main switch positioned at the back of the spotlight (lamp is on).
CAUTION: DO NOT OPEN THE FIXTURE UNTIL THE LAMP
HAS BEEN SWITCHED “OFF” FOR AT LEAST 30 MINUTES
13. SPOTLIGHT SETUP
If you have purchased a metal halide unit (Canto 575, Canto 700, Canto 1200) we strongly recommend
you check the lamp alignment of your followspot as follows:
a. Switch on the unit and project the beam on a flat surface (a wall, for example) at a short distance
(three to six feet/one to two meters).
b. Completely de-focus the zoom lenses so that you can see the lamp projected on the surface.
c. Close the douser (front lever) to a slightly bigger size than the height of the lamp. You should obtain
a circle of light including the projection of the lamp.
d. If the lamp is not exactly centered in the circle, using a phillips screwdriver, set the alignment by
alternately loosening or tightening each of the three adjusting screws located at the bottom of the
holder block (see illustration) until the bulb is perfectly aligned.

Adjusting
Screws
CAUTION: adjust each screw very slowly in order to prevent the bulb from touching
the optical system, as direct contact could cause both the bulb and the lenses to explode.
Once the alignment is correct you can start using your followspot.
NOTE: There are (6) screw heads visible
on the bottom of the bulb holder block.
The screws with lockwashers are mount-
ing screws; the screws with flatwashers are
the three adjusting screws.

14. FOCUSING
This fixtures features a variable beam angle from 8° to 22°. The variable beam is altered by adjusting the
front and rear zoom lenses in relation to each other. The front lens defines the beam spread (spot size),
the rear lens the focus degree of “softness” or “hardness” of the beam edge or shutters.
15. FADE-OUT MECHANICAL DIMMER (DOUSER)
The followspot is fitted with an adjustable mechanical dimmer to dim and finally douse the beam. The
fade-out/douser mechanical control lever is located between the two zoom lenses.
16. CLEANING AND MAINTENANCE
To insure maximum performance of the product, regular maintenance service should be carried out.
Please make sure the spotlight has cooled and is disconnected from its power source when doing this.
General Maintenance
• Clean all reflective parts such as reflectors, mirrors and lenses. Open the housing if necessary.
• Check the bulb and the lenses and replace any visibly damaged component.
• Clean air ducts and fans in order to allow proper ventilation.
• Check internal and external wiring and replace any cable which appears to be damaged by heat or
mechanical agents.
Cleaning of Optical Components
• Lamphouse lenses:
a. Remove the bulb.
b. Open the lamphouse compartment access panel by removing the two 4mm cross-head screws on the
top of the lamphouse tube.
c. Dismount the lens/mirror assembled block by removing the two 5mm cross-head screws.
d. Clean the lens/mirror assembly with a soft cloth through the top opening. To remove the lens/mirror
assembly from the lamphouse, see “Replacement of Cooling Fan” below.
• Zoom lenses:
Access the lenses through the sliding doors located on the bottom of the lens tube and clean with a
soft cloth.
Replacement of Cooling Fan
