Our 660nm Red Phosphor Powdera specialized nitride-based luminescent material engineered exclusively for high-power LED lighting systems operating at 100W and above. Designed to maintain stable performance under extreme heat while delivering warm, low color temperature (CCT＜3000K) illumination, this phosphor addresses the critical challenges faced by manufacturers of high-wattage LED fixtures for commercial horticulture, outdoor sports lighting, and industrial applications.
By combining ≥100 lm/W luminous efficiency with 300°C thermal stability and precise 660nm wavelength emission, this phosphor enables reliable operation in demanding high-power environments where standard phosphors experience rapid degradation and color shift.
High-power LED fixtures (100W-500W) generate concentrated heat that causes rapid phosphor degradation in standard materials. Our nitride-based formulation withstands continuous operating temperatures up to 300°C with no light decay under 280°C continuous operation—extending fixture lifespan in applications like 200W outdoor high-mast lights and commercial grow light arrays where thermal stress is constant.
The 660nm emission peak (±1.0 nm precision) serves critical functions in high-power applications: enhancing photosynthesis efficiency in flowering/fruiting stages for commercial hydroponics, and providing warm red illumination for outdoor lighting that minimizes light pollution while maintaining visibility in sports stadiums and highway installations.
Maintains consistent CCT range of 2200K-3000K even under high drive currents (500mA+) commonly used in high-power fixtures—preventing the unwanted "color cooling" effect that occurs when standard phosphors shift toward higher CCT during extended high-intensity operation.
The 5-20 micron particle size range (typical 8-15μm) ensures uniform dispersion within high-power LED packages, eliminating localized "hot spots" that cause uneven light output and premature failure in large-area fixtures covering warehouses and agricultural facilities.
99.9% purity minimizes impurity-related defects that cause CCT drift and brightness variation in high-power LEDs—critical for manufacturers supplying large-scale projects requiring thousands of identical fixtures (stadium upgrades, vertical farming installations). Backed by 2-year shelf life under proper storage, supporting long-term inventory management without material degradation.
RoHS 2.0 compliant and CE certified with lead-free formulation, ensuring regulatory compliance for high-power LED products exported to European and North American markets.

Our 660nm red phosphor is specifically designed for high-power LED applications requiring thermal resilience and low color temperature:
High-power grow lights (150W-1000W) for commercial hydroponics, vertical farms, and greenhouse supplemental lighting. The 660nm wavelength directly supports photosynthesis during flowering and fruiting stages, while the low-CCT spectrum (2200K-3000K) reduces plant stress compared to cooler color temperatures. Thermal stability ensures consistent spectral output throughout 12-18 hour daily operation cycles.
Stadium lighting, sports field illumination, and outdoor arena fixtures operating at 200W-500W. The warm red spectrum improves visibility without excessive glare, while 300°C thermal stability maintains performance through temperature fluctuations in unconditioned outdoor environments. Low-CCT output reduces light pollution affecting surrounding residential areas.
High-mast lights and roadway illumination fixtures (100W-300W) where warm color temperature enhances visibility of road markings and signage while reducing harsh blue-white glare that causes driver fatigue during extended nighttime use.
Large factory and warehouse fixtures (100W-200W) covering expansive spaces where uniform high-intensity illumination is required for safety and productivity. The ≥100 lm/W efficiency reduces energy consumption in facilities operating lighting 24/7.
Medical phototherapy equipment requiring precise 660nm wavelength, and professional stage lighting where low-CCT warm red creates specific atmospheric effects during extended performance periods.
Based on high-power LED packaging requirements:
COB (Chip-on-Board) High-Power Packages: 8-12 μm range for optimal thermal conductivity and uniform dispersion across large LED arrays
High-Power SMD Packages: 10-15 μm range for compatibility with automated dispensing equipment used in high-volume production
Custom High-Wattage Designs: Particle size optimization available for specialized fixture architectures requiring specific thermal or optical characteristics
To maximize performance in high-power LED manufacturing:
For low-CCT applications, combine with yellow phosphor (YAG:Ce³⁺) and adjust ratios based on target CCT and fixture wattage. Contact our technical team for formulation recommendations specific to your power output requirements and thermal management design.
Use vacuum degassing and controlled stirring speeds appropriate for high-viscosity silicone formulations used in high-power packages. Maintain uniform particle distribution to prevent localized thermal stress points in high-wattage fixtures.
Ensure LED package design incorporates adequate heat sinking—our phosphor maintains stability at 300°C, but optimal fixture lifespan requires keeping junction temperatures below 150°C through proper thermal design.
Compatible with high-temperature silicone encapsulants requiring curing up to 150°C. Verify curing profile compatibility with your specific encapsulant to prevent thermal shock during manufacturing.

A: The 300°C thermal stability and resistance to light decay under 280°C continuous operation prevent the rapid degradation that occurs with standard phosphors in high-wattage fixtures where heat concentration is unavoidable. The uniform particle size distribution (5-20 μm) also eliminates hot spots in large LED arrays.
A: Yes. We provide 10-50g evaluation samples for qualified B2B manufacturers, including spectral analysis reports verifying 660nm wavelength and low-CCT performance characteristics. Free samples available for qualified clients (shipping costs apply).
A: Our nitride formulation offers higher luminous efficiency (≥100 lm/W) and superior thermal stability (300°C vs. typical 200°C for silicates), making it more cost-effective for long-lifespan high-power LEDs that operate continuously under thermal stress.
A: Optimized for 450-460 nm excitation wavelength (peak: 658.1 nm), compatible with standard blue LED chips used in high-power packages. The 445-465 nm range is also applicable with minor efficiency variation.
A: The phosphor maintains consistent 2200K-3000K color temperature even under drive currents exceeding 500mA, preventing the unwanted color shift toward cooler temperatures that occurs with standard phosphors during extended high-intensity operation.
A: We provide a 30-day quality guarantee. If the phosphor causes CCT drift exceeding ±200K or light decay exceeding 5% in your high-power fixtures under specified operating conditions, we offer free replacement or full refund.
