The Stairville Stage Flood Inst QCL 48x10W is a professional LED floodlight designed for stage lighting. Key operational aspects include DMX control, Master/Slave configuration, and various pre-programmed automatic shows. Ensure the device is installed securely with a secondary safety attachment and that all electrical connections are performed by qualified personnel.
Safety instructions
- Electrical safety: Always use properly insulated, three-core mains cables. Do not modify the cable. Ensure the device is turned volt-free before maintenance.
- Heat and ventilation: The device surface becomes hot. Ensure adequate ventilation and keep illuminated surfaces at least 2 meters away. Do not operate in ambient temperatures above 40 °C.
- IP65 Rating: The device is dust-tight and protected against splash water. It is designed for temporary event lighting, not permanent outdoor installation. Regularly check seals and screw connections.
- Children: Keep packaging and small parts out of reach to prevent choking hazards.
Installation
The device can be installed on walls, ceilings, or floors using the included mounting bracket. Always secure the device with a secondary safety attachment (e.g., safety cable or chain). When lifting, hold the device only by the base to avoid damaging the rotatable mounting.
Connections and controls
The device features an LC display with four buttons (MENU, ENTER, UP, DOWN) for configuration. Connections include DMX input/output and power input/output. Use special DMX cables for data transfer; do not use standard microphone cables.
Operating modes
- Static colour: Set individual intensity for Red, Green, Blue, White, and Strobe effect.
- Automatic shows: Choose between 10 pre-programmed shows (Aut.) or 10 editable programs (Pro.).
- DMX mode: Supports 3, 6, 7, 8, 9, 10, or 15-channel modes. Set the DMX address via the menu to match your controller.
- Master/Slave: Connect multiple units in a daisy chain; the master unit controls the others.
Cleaning and maintenance
Regularly clean the optical lenses to maintain light output. Use a soft cloth and a dedicated lamp/lens cleaner (item no. 280122). Always dry parts carefully after cleaning.
