    1W 3W 385nm 395nm UVA LED SMD3535 UV Curing Light 3D ...
    3W UV curing LEDs are compact, high-intensity light sources (commonly 365nm, 395nm, or 405nm) used for curing UV-sensitive inks, coatings, and resins in printing and industrial applications. These 3W LEDs (like 3535 SMD types) offer high-power curing for printing, coating, adhesive bonding, and 3D resin curing. 
    Key Features of 3W UV Curing LEDs 
    • Wavelengths: Available in 365nm, 385nm, and 395-400nm to match different ink and coating requirements.
    • Efficiency: Designed for high current operation and high power output, allowing for fast curing, sometimes in 10-15 seconds for resin.
    • Applications: Ideal for UV curing, printing, coatings, adhesive application, and DIY resin curing stations.
    • Power Requirements: They require a constant current LED driver and should be mounted on a heatsink or thermal PCB to prevent failure due to heat. 
    Application in Printing and Coating 
    • UV LED Printing: These LEDs are used in printing to instantly cure inks, increasing production speed and reducing smudging.
    • Coating & Curing: They are used to cure coatings on materials, including plastic moldings, panels, and furniture, offering high scratch resistance.
    • 3D Printing: 3W UV LEDs are commonly used in DIY resin curing boxes for hardening SLA/DLP 3D prints. 
    Common Specifications 
    • Power: 3W
    • Voltage: 3.4-3.6V
    • Current: ~700mA
    • Lifespan: Often rated for >50,000 hours if kept under
      60∘C60 raised to the composed with power C
      60∘C
       
    Important Precautions 
    • Eye Safety: Do not look directly at the LED light within two meters to avoid eye damage.
    • Thermal Management: Must use a heatsink, otherwise the LED will fail from heat. 
    Products like the Portable 3W UV Light from Counter Culture DIY are available for small-scale applications.
