For LED manufacturers facing thermal degradation in high-power fixtures or growers demanding precise red spectrum control for flowering cycles, our 660nm red LED phosphor solves critical performance bottlenecks. Engineered with (Sr,Ca)AlSiN₃:Eu²⁺ chemistry and optimized for 445-465nm blue LED chips, this phosphor delivers 100 lm/W luminous efficiency while maintaining stable output during continuous operation at 300°C—addressing heat-induced brightness loss in stadium lighting, industrial high-bays, and vertical farming systems. With ISO-certified manufacturing, RoHS compliance, controlled particle size (D50=15.5±2.0μm), and proven compatibility with standard LED packaging processes, this phosphor enables energy-efficient, thermally reliable lighting solutions with full test documentation for quality assurance.
Product Advantages
High Luminous Efficiency for Reduced Operating Costs
With 100 lm/W efficiency (measured at 25°C, 350mA), this phosphor minimizes power consumption in LED fixtures—directly reducing electricity costs for end-users operating high-power or continuous-use lighting. The narrow emission bandwidth (FWHM 74±1nm) centered at 627.4nm ensures minimal energy waste through spectral spillover, while maintaining high brightness output. For manufacturers targeting energy-regulated markets, this efficiency level supports compliance with standards such as the EU ErP Directive.
Exceptional Thermal Stability for High-Power Applications
Engineered to withstand continuous operation at 300°C and peak temperatures up to 500°C, this nitride phosphor maintains stable luminous output in high-heat LED packaging environments. The cubic crystal structure of (Sr,Ca)AlSiN₃:Eu²⁺ resists thermal quenching—a common failure mode in high-power fixtures where junction temperatures exceed 150°C. This thermal reliability extends fixture lifespan and reduces warranty costs for manufacturers serving industrial, sports, and transportation lighting sectors.
Optimized Red Spectrum for Horticultural and High-CRI Lighting
The 610-670nm emission range (peak: 627.4±2.0nm) aligns with chlorophyll B absorption peaks, making this phosphor highly effective in commercial grow lights for flowering and fruiting stages. In architectural and retail lighting, it combines with yellow-green phosphors (535nm) to achieve 85+ CRI values, ensuring accurate color rendering. This spectral versatility eliminates the need for multiple phosphor inventories, streamlining production for manufacturers serving diverse lighting sectors.
ISO-Certified Quality with Full Test Documentation
Our phosphor is manufactured under ISO quality management systems, ensuring batch-to-batch consistency critical for large-scale LED production. Every bulk order includes comprehensive test reports covering luminous efficiency, spectral distribution, particle size analysis, and thermal stability data—enabling your quality assurance team to verify performance before integration. This documentation also supports customer audits and regulatory compliance in global markets.
Process-Ready Design and Global Compliance
Particle size control (5-20 microns, D50=15.5±2.0μm) ensures uniform dispersion in silicone binders, minimizing "color spotting" in LED arrays. The phosphor is lead-free and RoHS-compliant, facilitating market access in North America, EU, and other regulated regions. Optimized for 445-465nm blue LED chips—the industry standard—it integrates seamlessly into existing production lines without requiring chip or packaging modifications.

Application Scenarios
Our 660nm red phosphor serves multiple high-demand LED applications, offering thermal reliability and spectral precision:
High-Power LED Fixtures
Suitable for stadium lighting, industrial high-bay lamps, and highway illumination where continuous high-temperature operation is required. Thermal stability at 300°C prevents the brightness degradation commonly seen in fixtures exceeding 100W power draw, minimizing maintenance cycles and warranty claims.
Commercial Horticultural Lighting
The 610-670nm spectrum supports plant flowering and fruiting stages in vertical farms, greenhouse supplemental lighting, and hydroponic systems. Growers targeting specific crop responses (such as cannabis flowering or tomato fruit set) benefit from precise spectral control, while high efficiency reduces operating costs in 24/7 grow room environments.
High-CRI Architectural and Retail Lighting
When blended with yellow-green phosphors, achieves 85+ CRI for color-accurate illumination in retail displays, art galleries, and hospitality environments. Narrow FWHM ensures saturated red tones without the muddy appearance of broadband phosphors.
Integrated LED Modules
Compatible with COB (chip-on-board) and direct-attach packaging used in downlights, track lighting, and automotive interior illumination. Controlled particle size prevents sedimentation during manufacturing, ensuring uniform color across production batches.
Stage and Entertainment Lighting
Uniform color mixing supports vibrant red hues in theatrical fixtures and architectural accent lighting. High efficiency enables compact fixture designs with reduced heat sink requirements.

Packaging and Integration Guidelines
To achieve optimal performance in LED production, we recommend the following handling and formulation practices:
Phosphor Blending
For high-CRI white LEDs, combine red phosphor with yellow-green phosphor (535nm) in ratios adjusted for target CCT (e.g., 1:4 for 3000K warm white). For grow lights, pair with 450nm blue chips without additional phosphors.
Silicone Compatibility
This phosphor is tested with standard LED-grade silicones. Use low-viscosity silicones (≤5000 cps) for uniform dispersion, and vacuum degas before curing to eliminate air bubbles.
Curing Parameters
Cure at 150-180°C for 1-2 hours. Avoid exceeding 200°C during any processing step to maintain phosphor efficiency.
Storage Conditions
Store in sealed containers at 15-25°C, relative humidity ≤60%. Avoid exposure to acids, bases, or direct sunlight. Shelf life is 24 months under proper storage.
Anti-Settling Tips
For high-volume production, use thixotropic silicone additives to prevent phosphor sedimentation during pre-cure phases.

Is this phosphor compatible with my existing blue LED chips?
It is optimized for 445-465nm blue LEDs, which represent the majority of commercial LED production. If you use chips outside this range, we offer free compatibility testing—send us your chip specifications, and we'll provide photometric analysis within 5 working days.
What makes nitride phosphors suitable for high-power applications?
The (Sr,Ca)AlSiN₃:Eu²⁺ crystal structure resists thermal quenching better than silicate or garnet phosphors, maintaining stable output at elevated temperatures. This addresses the common failure mode in high-power fixtures where LED junction temperatures exceed 150°C, causing brightness loss and color shift in standard phosphors.
