3. Opsætning og installation
3.1 Udpakning og første inspektion
Carefully remove all components from the packaging. Inspect for any signs of damage during transit. Ensure all listed components are present.
3.2 Assembly of Light Bars and Driver
The VSFL6450 features a foldable design. Gently unfold the light bars to their full extension. The power supply (driver) is detachable for easier maintenance and improved heat dissipation. Secure the driver to the light fixture using the provided screws if it is not pre-attached.

Video 3.2: This video provides a general installation guide for an AGLEX M600 grow light, which shares similar bar-style construction and assembly principles with the VSFL6450.
3.3 Hanging the Light
Attach the provided rope hangers to the designated points on the light fixture. Use the hangers to suspend the light securely from a sturdy support structure within your grow tent or cultivation area. Adjust the rope hangers to achieve the desired distance between the light and your plants.

3.4 Elektrisk tilslutning
Connect the power cord to the detachable power supply, then plug the power cord into a grounded electrical outlet. Ensure the voltage matches the product specifications (100-277V).
4. Betjening
4.1 Powering On/Off and Dimming
The light can be powered on/off and dimmed using the manual knob on the detachable power supply. The knob offers 6 levels of light intensity: 40%, 50%, 60%, 80%, 100%, and EXT (external control).

4.2 Full Spectrum with UV/FR
The VSFL6450 provides a full spectrum of light from 380-780nm, including 450nm blue light, 660nm deep red, 730nm far red, and photosynthetic UVA. This spectrum is optimized for all stages af plantevækst:
- Blåt lys: Promotes germination and vegetative growth.
- Varmt hvidt lys: Encourages flowering.
- Red Light (Deep Red & Far Red): Essential for higher potency and fruit development.
- DRUER: Contributes to overall plant health and secondary metabolite production.

4.3 Daisy Chain and Intelligent Control
The VSFL6450 can be daisy-chained with up to 160 units, making it suitable for larger cultivation setups. For advanced control, connect the light to a VIVOSUN GrowHub Controller using an RJ11 cable. The GrowHub Controller, accessible via the VIVOSUN App, enables features such as:
- Remote control of light intensity.
- Time slot programming for precise on/off times.
- PPFD mode for maintaining a target light level (requires GGS Sensor Pro).
- High Temperature Protection to automatically dim or turn off the light.
- Sunrise/Sunset simulation for natural light patterns.
