How to Buy 400W COB LED Chip

## How to Buy 400W COB LED Chip.

### 1. What is a 400W COB LED Chip?

A **400W COB (Chip on Board) LED chip** is a high-power light-emitting diode used in lighting applications. It combines multiple LED chips mounted on a single substrate to create a powerful and efficient light source.

### 2. What are the key features to consider when buying a 400W COB LED chip?

When purchasing a **400W COB LED chip**, you should consider several important features:

- **Luminous Efficiency**: The amount of light produced per watt of power consumed. Higher efficiency means more light output with less energy.

- **Color Temperature**: Measured in Kelvin (K), it determines the color of the light emitted. Common temperatures range from warm white (2700K) to cool white (6500K).

- **The Beam Angle**: The spread of the light emitted. Wider angles are suitable for general lighting, while narrower angles are ideal for focused lighting.

- **Thermal Management**: Effective heat dissipation is crucial to maintaining performance and lifespan. Look for chips with good thermal management systems.

- **Lifespan**: Typically measured in hours (e.g., 50,000 hours). Higher lifespan means longer-lasting performance.

- **CRI (Color Rendering Index)**: A measure of how accurately the light source renders colors. Values above 80 are generally good for most applications.

- **Voltage and Current Requirements**: Ensure compatibility with your power supply and system.

### 3. Where can you buy a 400W COB LED chip?

You can purchase 400W COB LED chips from various sources, including:

- **Online Retailers**: Websites such as Amazon, eBay, and specialized electronics stores.

- **Manufacturer Websites**: Directly from manufacturers like Cree, Bridgelux, or Citizen.

- **Electronics Supply Stores**: Both online and brick-and-mortar outlets that specialize in electronic components.

- **Wholesale Suppliers**: For bulk purchases, providers like Alibaba or AliExpress are suitable options.

### 4. How to evaluate the quality of a 400W COB LED chip?

To ensure you are buying a high-quality **400W COB LED chip**, follow these steps:

- **Check Specifications**: Carefully review the datasheet provided by the manufacturer.

- **Read Reviews**: Look for customer feedback and product reviews to gauge reliability and performance.

- **Consider Brand Reputation**: Established brands with positive reputations often provide more reliable products.

- **Ask for Samples**: If possible, testing a sample can provide a firsthand evaluation of quality and suitability.

- **Warranty and Support**: Ensure the product comes with a warranty and access to customer support.

### 5. What are the common applications of a 400W COB LED chip?

A **400W COB LED chip** is versatile and can be used in various applications such as:

- **Industrial Lighting**: Factories, warehouses, and workshops where high-intensity and durable lighting is required.

- **Commercial Lighting**: Retail spaces, offices, and large commercial buildings.

- **Residential Lighting**: High-end home lighting solutions, particularly in large spaces or for architectural purposes.

- **Outdoor Lighting**: Street lamps, floodlights, and sports facilities.

- **Specialty Lighting**: Stage lighting, horticultural lighting for indoor farming, and other specialized environments.

### Conclusion.

Buying a **400W COB LED chip** involves understanding key features, evaluating quality, and identifying reliable suppliers. By considering factors like luminous efficiency, color temperature, and thermal management, you can choose the right chip for your application. Researching suppliers and checking reviews will help ensure you make a well-informed purchase.
