4.1 Operation

The lamp used for Arco 650/1000 is a 650W or 1000W halogen lamp GX9.5 base.

The PC lens version gives an intense and precise beam of light, whereas the Fresnel lens provides a diffuse out-

put, giving a soft edge to the beam.

4.2 Beam angle

To adjust the beam angle turn the knob located on the rear side of the lantern.

Turning the knob clockwise will reduce the angle whereas turning it anti-clockwise will increase the angle.

4.3 Colour frame

The colour frame is fitted in the two guide slots provided on the front of the lantern.

High-temperature resistant colour filter is recommended.

4.4 Accessories

A 4-leaf barndoor is supplied as an accessory and it must be fitted in the guide slots of the colour frame.

To ensure maximum functionality and light output it is recommended to follow these instructions:

• clean lens and reflector regularly, as even a thin layer of dust can reduce the light output and scatter the beam;

to access the lens remove the safety guard located on the front part of the spotlight.

• replace the lamp if it has become damaged or it's thermally deformed;

• carefully check the electrical connections, particularly the earth connection;

• replace the lenses if they have become visibly damaged;

• replace all the damaged components
