3535 High Power Red SMD LED, 620nm 660nm Dome Lens 1W LED Chip for Medical Beauty Therapy & Indoor Plant Growth Lighting

High-performance 3535 red SMD LED with spherical dome lens, available in 620nm and 660nm therapeutic wavelengths, 1W rated power with stable optical output. Excellent thermal dissipation design ensures long lifespan, ideal for medical phototherapy equipment, beauty devices and full-spectrum plant grow light fixtures, SMT compatible with standard tape reel packaging.

Our 3535 high-power red SMD LED is a professional-grade light source optimized for medical phototherapy and horticultural lighting applications. It features a high-quality red LED die encapsulated in a clear silicone spherical dome lens, mounted on a high thermal conductivity substrate for reliable heat management. Available in two core therapeutic wavelengths: 620nm (deep red for skin care) and 660nm (far red for plant photosynthesis), this LED delivers uniform and consistent red light output. Standard 3535 footprint supports fully automatic SMT assembly, making it suitable for mass production of medical beauty devices and commercial plant grow lights.

• Dual Therapeutic Wavelengths: Two optimized red wavelengths available to meet different application requirements: 620nm for skin rejuvenation and 660nm for plant photosynthesis enhancement.
• Dome Lens Optical Design: Spherical dome lens provides uniform light distribution and improved light penetration efficiency, perfect for both skin treatment and plant canopy illumination.
• Superior Thermal Performance: High thermal conductivity substrate effectively dissipates working heat, reduces junction temperature and suppresses light decay for long-term continuous operation.
• High Power Stable Output: 1W high-brightness design delivers sufficient light intensity, reducing the number of LEDs required per fixture and lowering overall system cost.
• Standard 3535 Form Factor: Universal industry size compatible with existing automated SMT production lines, enabling high-volume manufacturing with consistent quality.
• Reliable Encapsulation: Robust silicone encapsulation resists moisture and temperature fluctuations, suitable for both indoor medical and horticultural environments.

• 1. Medical & Beauty Phototherapy
  • LED facial beauty masks, skin rejuvenation devices, wound healing instruments, anti-aging phototherapy lamps, medical rehabilitation equipment.
• 2. Horticultural Plant Lighting
  • Indoor plant grow lights, hydroponic lighting systems, greenhouse supplementary lights, vertical farm illumination, seedling growth lamps.
• 3. Other Applications
  • Industrial indicator lights, traffic signal modules, decorative red lighting fixtures, customized special red light sources.

• Packing: Standard tape-on-reel packaging with aluminum moisture-proof vacuum bag; customized reel quantity is available for large bulk OEM orders.
• Storage: Store unopened LED components in a dry environment at 0~30℃ with relative humidity below 60%; complete full consumption within 24 hours once unpacked to prevent chip damage from moisture ingress.
• Handling: Proper ESD protection measures must be implemented during assembly to avoid electrostatic damage to the LED chips.
