5. Setup and Installation
This fixture is designed for suspension mounting. Ensure the mounting surface can support the weight of the fixture(s) and that all electrical connections are made safely.
5.1 Tools Required (Not Included):
- Drill
- Screwdriver (Phillips and Flathead)
- Wire Strippers
- Measuring Tape
- Pencil
- Safety Glasses
5.2 Installation Steps:
- Power Disconnection: Turn off power at the circuit breaker before starting installation.
- Marking Mounting Points: Determine the desired location for the fixture(s). Use a pencil to mark the ceiling for the suspension cable anchors. For multiple linked fixtures, ensure proper spacing.
- Install Ceiling Anchors: Drill pilot holes at the marked points and insert appropriate ceiling anchors. Secure the ceiling mount hardware.
- Attach Suspension Cables: Attach the suspension cables to the ceiling mount hardware. The cable length is adjustable up to 79 inches (approx. 6.5 ft).
Figure 5.1: Suspension hardware and adjustable cable length.
Figure 5.2: Detail of the adjustable suspension cable mechanism.
- Hang the Fixture: Carefully attach the linear light fixture to the suspension cables. Adjust the cable length to achieve the desired hanging height.
- Electrical Wiring: Connect the fixture's wiring to the main power supply. This fixture is designed for hardwiring. Follow standard electrical codes for connecting Live, Neutral, and Ground wires. If using 0-10V dimming, connect the purple (DIM+) and gray (DIM-) wires to the compatible dimmer.
- Linking Multiple Fixtures (Optional): If installing multiple fixtures in a continuous run, use the provided linking connectors. Ensure power is disconnected before linking. Connect the fixtures mechanically using the linking plates and electrically using the internal wiring connectors.

- Restore Power: Once all connections are secure and the fixture(s) are properly mounted, restore power at the circuit breaker.
6. Operating Instructions
6.1 Color Temperature Selection (CCT)
The DAKASON Linear Light allows you to select from three color temperatures: 3000K, 4000K, or 5000K. This selection must be made before installation by accessing the switch located on the fixture.
- Locate the CCT selection switch on the side of the fixture.
- Use a small tool (e.g., screwdriver) to slide the switch to your desired color temperature: 'W' for 3000K, 'CW' for 4000K, or 'C' for 5000K.
- Ensure the switch is firmly set in the chosen position.

6.2 Dimming Functionality
This fixture is compatible with 0-10V dimmers (not included). To utilize the dimming feature, ensure your electrical system includes a compatible 0-10V dimmer switch and that the fixture's dimming wires (purple and gray) are correctly connected during installation.
- Once installed with a 0-10V dimmer, use the dimmer switch to adjust the brightness from 0% to 100%.
- The fixture is designed for smooth dimming without flickering or buzzing.
