3. Setup
3.1 Charging the Device
The VL49 RGB Pro has a built-in 2500mAh battery. Before first use, fully charge the device.
- Connect the provided Type-C charging cable to the Type-C charging port on the side of the light.
- Connect the other end of the cable to a 5V/1A USB power adapter (not included).
- The charging time is approximately 4 hours for a full charge.

3.2 Mounting Options
The VL49 RGB Pro offers flexible mounting solutions:
3.2.1 Cold Shoe Mount
Attach the double-headed cold shoe mount to the 1/4 standard screw port on the bottom of the light. This allows you to mount the light onto cameras, camera cages, or other accessories with a cold shoe slot.

3.2.2 Magnetic Adsorption
The light features a four-sided magnetic adsorption design, allowing it to be firmly attached to iron surfaces. This provides flexibility for creative lighting setups.

Attention: Do not adsorb the magnet on surfaces where the temperature exceeds 80°C to prevent the magnetic force from declining.
4. Operating Instructions
4.1 Controls Overview
Familiarize yourself with the control buttons and display screen:

- Power Button: Turns the device on/off.
- Mode Button: Cycles through different lighting modes (RGB, CCT, FX).
- Switching Button: Used to switch between parameters within a mode (e.g., H, S, I in RGB mode; K, Brightness in CCT mode).
- Adjustment Buttons (+/-): Increases or decreases the selected parameter value.
- Display Screen: Shows current settings like HSI values, color temperature, and brightness.
4.2 Lighting Modes
The VL49 RGB Pro offers three main lighting modes:
4.2.1 RGB Mode (HSI)
In RGB mode, you can adjust the Hue (H), Saturation (S), and Intensity (I) to achieve any color in the 360-degree spectrum.

- Press the Mode button until 'RGB' is displayed.
- Use the Switching button to select between H (Hue), S (Saturation), and I (Intensity/Brightness).
- Use the Adjustment buttons (+/-) to change the values:
- H (Hue): 0-360° (full color spectrum)
- S (Saturation): 0-100% (color purity)
- I (Intensity/Brightness): 0-100% (light output)
4.2.2 CCT Mode (Color Temperature)
In CCT mode, you can adjust the color temperature from warm yellow to cool white light.

- Press the Mode button until 'CCT' is displayed.
- Use the Switching button to select between Color Temperature (K) and Brightness (%).
- Use the Adjustment buttons (+/-) to change the values:
- Color Temperature: 2500K (warm) to 9000K (cold)
- Brightness: 0-100%
4.2.3 FX Mode (Dynamic Light Effects)
The FX mode offers 20 kinds of simulated light effects for creative shooting scenarios.

- Press the Mode button until 'FX' is displayed.
- Use the Switching button to cycle through the 20 available effects.
- Use the Adjustment buttons (+/-) to modify parameters specific to each effect (e.g., speed, intensity).
Available effects include: Cop Car, Fireworks, Fault Bulb, Paparazzi, Green Flash, Ambulance, TV, Pulsing, Emergency, Blue Flash, Fire Engine, Candle, Strobe, H/L Beam, HSI Slow, Lightning, Party, RGB Strobe, Red Flash, HSI Fast.
5. Maintenance
- Cleaning: Use a soft, dry cloth to clean the light. Do not use harsh chemicals or abrasive materials.
- Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: To prolong battery life, avoid fully discharging the battery frequently. Charge it regularly, even if not in use for extended periods.
- Magnetic Adsorption: As noted in setup, avoid exposing the magnetic surfaces to temperatures exceeding 80°C to maintain magnetic strength.
6. Troubleshooting
- Light not turning on: Ensure the battery is charged. Connect to a power source and try again.
- Light not charging: Check the Type-C cable and power adapter for damage. Try a different cable or adapter.
- Light flickering or inconsistent output: The battery might be low. Recharge the device. If the issue persists, contact customer support.
- Magnetic adsorption weakening: Ensure the light has not been exposed to high temperatures (above 80°C) for prolonged periods.
