2835 LED Chips​

The 2835 LED chip is a popular choice for horticultural lighting due to its high luminous efficacy and reliability. Measuring 2.8mm x 3.5mm, this chip is designed to provide a balanced spectrum that supports both vegetative and flowering stages of plant growth. Key advantages of the 2835 LED chip include:

High Efficiency: Capable of delivering high light output with lower power consumption, making it energy-efficient.

Thermal Management: Excellent heat dissipation properties, which are crucial for maintaining performance and longevity.

Cost-Effectiveness: Provides a good balance between performance and cost, making it accessible for large-scale horticultural applications.

3030 LED Chips​

The 3030 LED chip, with dimensions of 3.0mm x 3.0mm, is renowned for its robustness and higher power handling capabilities. This chip is particularly suitable for applications requiring high light intensity. Its attributes include:

High Power Output: Suitable for high-intensity lighting applications, ensuring deep canopy penetration.

Durability: Designed to withstand harsh operating conditions, including high humidity and varying temperatures common in greenhouses and indoor farms.

Versatility: Available in various color temperatures and wavelengths, allowing for customized lighting solutions tailored to specific plant needs.

3535 LED Chips​

The 3535 LED chip, measuring 3.5mm x 3.5mm, is one of the most advanced options for horticulture lighting, offering superior performance characteristics. Its benefits include:

High PPE: Capable of delivering very high light output, making it ideal for professional horticultural environments.

Excellent Sulfur resistance: Provides precise control over the light spectrum, which can be optimized for different growth stages and plant species.

Reliability: Built to last, ensuring consistent performance over long periods, which is essential for commercial growers.

Comparative Analysis：

When selecting the appropriate LED chip for horticultural lighting, several factors need to be considered:

Application Requirements: For general-purpose lighting, the 2835 LED chip is often sufficient. For high-intensity lighting needs, the 3030 and 3535 chips are more suitable.

Energy Efficiency: All three chips offer high energy efficiency, but the 2835 chip is particularly noted for its lower power consumption.
