Function Description
The GVM-PRO-SD200B and GVM-PRO-SD300B are high-definition COB LED lights engineered to restore and enrich the color of objects, providing natural and vivid shooting effects.

- Light Source Matching Mode: This mode provides 12 different styles of light source types. This feature is particularly useful when a specific light source simulation is required, saving significant adjustment time.
- Light Effect Mode: This mode offers 12 pre-programmed light effects to enhance creative shooting scenarios. These effects include Lightning, CCT Loop, Candle, Bad Bulb, TV, Paparazzi, Explosion, Pulsing, Strobe, Fire, Fireworks, and Welding, providing a wide range of dynamic lighting options.
Usage Features
Safety Instructions:
Before using the product, it is crucial to read the manual carefully. The device is designed for use within a temperature range of -20°C to 45°C. It should not be placed near flammable or volatile solvents like alcohol and gasoline. After use, ensure the device has cooled down completely before storing it. Always unplug the power cord during storage, and keep the equipment in its carrying case or a well-ventilated, dry place.
This lighting fixture is not intended for general illumination. Individuals with eye injuries or sensitivity should avoid using it. It is a professional light, and children are prohibited from using it without close supervision to prevent personal injury. Always remove the protective cover before operation. When the light is on, never stare directly at the light source due to its high intensity. High-intensity lighting should only be used under the guidance of a professional lighting technician. If any discomfort is experienced, immediately turn off the light and seek medical attention. Handle the fixture carefully when on, avoiding contact with high-temperature components like the LED light source to prevent burns.
Do not use damaged equipment or accessories. Any repairs should be performed by a professional repairman. If the light source is damaged or deformed by heat, cease use immediately and contact the manufacturer or a qualified repairman for replacement. If the product is cracked due to falling, squeezing, or strong impact, discontinue use to avoid electric shock from internal electronic components. Do not disassemble the product; malfunctions should be checked and repaired by the manufacturer or authorized personnel. Before cleaning or maintenance, always unplug the power supply by pulling the plug, not the cable. The device must only be operated with earthed power outlets or emergency power generators.
When cleaning, use a dry, soft cloth; do not use wet cloths. If an extension cord is needed, ensure it has adequate capacity to prevent overheating. For products with long power cords, route them properly to avoid contact with overheated surfaces or tripping hazards. Use only original power cords; damage from non-original cords is not covered by warranty. Avoid using accessories not recommended by the brand to prevent fire, electric shock, or personal injury.
For products using batteries, use only specified batteries, power sources, or accessories. Keep batteries and accessories out of reach of children. If a battery leaks, changes color, deforms, smokes, or emits an odor, remove it immediately, being careful to avoid burns. Do not use deformed or modified batteries, disassemble or modify the product or battery, heat or solder the battery, or expose it to fire, water, or strong external force. Ensure correct polarity when inserting batteries and do not mix old and new or different types of batteries. For products with built-in lithium batteries, use the dedicated charger and follow operating instructions within the prescribed voltage and temperature range.
