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.
