Package Contents
Verify that all components are present in the package:
- OPTONICA FL5848 LED Floodlight (non-replaceable bulb)
- Mounting Bracket
- Instruction Manual (this document)
Setup and Installation
Follow these steps for proper installation of your LED floodlight:
- Choose a Location: Select a suitable outdoor location for mounting. The recommended mounting height is 1.8 to 2.5 meters for optimal motion sensor performance. Ensure the area is clear of obstructions that might block the sensor's field of view.
- Power Disconnection: Before starting any electrical work, ensure the main power supply to the installation area is turned off at the circuit breaker.
- Mounting the Bracket: Use appropriate screws and wall plugs (not included) to securely fasten the mounting bracket to the desired surface. The bracket allows for angle adjustment.
- Wiring Connection: Connect the floodlight's power cable (approx. 25 cm) to your main electrical supply. Ensure correct polarity (Live, Neutral, Earth). All connections must be secure and insulated. This product operates on 170-265V, 50-60Hz.
- Attach the Floodlight: Secure the floodlight to the mounted bracket using the provided hardware. Adjust the angle of the floodlight to illuminate the desired area.
- Power Restoration: Once installation is complete and all connections are secure, restore power to the circuit.

Operating Instructions
The OPTONICA FL5848 features an integrated motion sensor with adjustable settings. The sensor has a detection angle of 120° and a detection range of 5-15 meters.
Motion Sensor Settings:
The motion sensor unit has three adjustable knobs:

Image: Detailed view of the motion sensor's adjustment knobs. From left to right, these are typically for TIME, SENS (Sensitivity), and LUX (Light Level).
- TIME (Delay Time): This knob controls how long the light stays on after motion is detected and no further motion is sensed. Adjustable from 12 seconds to 6 minutes. Turn clockwise to increase the duration.
- SENS (Sensitivity): This knob adjusts the detection range of the motion sensor, from 5 to 15 meters. Turn clockwise to increase sensitivity and detection range.
- LUX (Light Level): This knob determines the ambient light level at which the sensor will activate the floodlight.
- Turn towards the "sun" symbol (max LUX, 2000 Lux) for the light to activate during both day and night.
- Turn towards the "moon" symbol (min LUX, 3 Lux) for the light to activate only in low light conditions or darkness.
Testing the Sensor: After installation, set the TIME to minimum and LUX to maximum (sun symbol). The light should turn on when motion is detected. Once satisfied with the detection, adjust TIME and LUX to your desired operational settings.
Maintenance
The OPTONICA FL5848 LED Floodlight is designed for minimal maintenance. However, regular cleaning can help maintain optimal performance and appearance.
- Cleaning: Periodically clean the floodlight's surface and the motion sensor lens with a soft, damp cloth. Do not use abrasive cleaners or solvents, as they may damage the finish or sensor.
- Inspection: Occasionally check the mounting bracket and wiring connections for any signs of wear, corrosion, or loosening. Ensure the floodlight is securely fastened.
- LED Lifespan: The LED light source is designed for a long lifespan (average 25,000 hours) and is not replaceable. If the LEDs fail, the entire unit should be replaced.

Troubleshooting
If you encounter issues with your OPTONICA FL5848 LED Floodlight, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on. | No power supply. LUX setting too low (daylight). Sensor not detecting motion. | Check power connection and circuit breaker. Adjust LUX knob towards "sun" symbol. Check SENS setting and ensure no obstructions. |
| Light stays on continuously. | Constant motion in detection area. TIME setting too long. Sensor malfunction. | Clear detection area. Adjust TIME knob to a shorter duration. Contact customer support if problem persists. |
| Light flickers or is dim. | Unstable power supply. Damaged wiring. | Consult a qualified electrician to check power supply. Inspect wiring for damage (with power off). |
| Sensor not detecting motion effectively. | SENS setting too low. Mounting height incorrect. Obstructions in detection path. | Adjust SENS knob to increase sensitivity. Ensure mounting height is 1.8-2.5m. Remove any objects blocking the sensor's view. |
