5. Setup
- Unpacking: Carefully remove the fixture and all accessories from the packaging. Retain the packaging for future storage or transport.
- Attaching Barn Doors: The four barn doors can be easily attached to the front of the light fixture. Align the hinges of the barn doors with the designated slots on the light and secure them. These are designed to be adjustable to control light spill.
- Mounting: Attach the provided mounting bracket to the sides of the fixture using the included screws. The bracket allows for various mounting options, including floor mounting or truss mounting (clamp not included). Ensure the fixture is securely fastened to a stable surface or structure.
- Power Connection: Connect the power cable to the 'POWER IN' port on the rear of the fixture. Plug the other end into a suitable grounded power outlet.
- DMX Connection (Optional): If using DMX control, connect a DMX cable from your DMX controller to the 'DMX IN' port of the first fixture. For multiple fixtures, daisy-chain them by connecting the 'DMX OUT' of the first fixture to the 'DMX IN' of the next.
6. Operating Modes
The Betopper Par Light offers multiple control modes, accessible via the control panel on the rear of the unit. The control panel typically includes an LED display and buttons for MENU, UP, DOWN, and ENTER.

6.1. DMX Mode
DMX512 mode allows for professional control of the fixture's parameters (color, dimming, strobe, etc.) using an external DMX controller. Refer to the DMX channel chart (usually provided in a separate DMX manual or on the manufacturer's website) to understand the specific functions assigned to each DMX channel. Set the DMX address for each fixture using the control panel.
6.2. Automatic Mode
In Automatic mode, the fixture runs through pre-programmed internal light shows and color sequences. This mode is ideal for quick setup without the need for an external controller. Use the control panel to select different auto programs or adjust their speed.
6.3. Sound-Activated Mode
The Sound-Activated mode enables the fixture to react to ambient sound or music. An internal microphone detects sound, and the light effects change in sync with the beat. Adjust the sound sensitivity via the control panel if available.
6.4. Master-Slave Mode
This mode allows multiple fixtures to operate in synchronization without a DMX controller. Connect the fixtures in a daisy chain. Set one fixture as the 'Master' (e.g., in Auto or Sound-Activated mode), and the others as 'Slave'. The slave units will then mimic the master unit's behavior.
6.5. CRI Adjustment
The fixture supports adjustment of the Color Rendering Index (CRI) in specific modes to fine-tune color accuracy. To adjust CRI:
- Press the MENU button.
- Navigate to the CRI adjustment setting (e.g., 'Ct' or 'CRI' on the display) and press ENTER.
- Use the UP or DOWN buttons to adjust the CRI value (typically a range from 01-09).
- Press ENTER to confirm your selection.

7. Maintenance
- Cleaning: Regularly clean the lens and housing with a soft, lint-free cloth. For stubborn dirt, use a mild glass cleaner. Ensure the fixture is unplugged and cool before cleaning. Do not use abrasive cleaners or solvents.
- Inspection: Periodically inspect power cables, DMX cables, and mounting hardware for any signs of wear, damage, or loose connections. Replace damaged components immediately.
- Storage: When not in use, store the fixture in its original packaging or a suitable flight case in a dry, dust-free environment.
