10W Dual-Wavelength UV LED Bead (365nm + 395nm) on 20mm Aluminum Star Base - White

Specifications:

• Power Rating: 10 Watts
• Dual-Spectrum: 365nm (UVA) + 395nm (Near-UV)
• Base Material: 20mm Aluminum Plate (White)
• Input Voltage (Forward Voltage): 9.0V - 11.0V DC
• Forward Current: 900mA - 1000mA
• Luminous Intensity: 100-120 LM
• Viewing Angle: 120 - 140 Degrees
• Operating Temperature: -20°C to 60°C (Requires additional heatsink)

Key Applications & Projects

• Industrial Curing: Instant bonding of UV-sensitive resins and glass glues.
• Forensics & Security: Identifying counterfeit currency, forensic fluids, and security watermarks.
• Mineralogy: Fluorescing reactive minerals that only respond to 365nm light.
• Leak Detection: Using UV dyes to find leaks in HVAC or automotive systems.

Project Evolution 

• Past Projects (Prerequisites): If you have used standard 5mm UV LEDs or 3W UV beads and found the curing time too slow or the fluorescence too dim, this is your next step.
• Feature Upgrade: This 10W module provides roughly 10x the radiant flux of standard LEDs. The dual-wavelength architecture allows it to cure a wider variety of "Fast-Cure" and "Hard-Cure" resins simultaneously.
• Effort Level: Intermediate. Requires a constant current LED driver and a secondary heatsink.

Virtual Technician: Wiring & Safety Guide 

⚠️ WARNING: High-power UV radiation is harmful to eyes and skin. Always wear UV-rated safety goggles. Wiring Guide:

• Positive (+): Connect to the V+ of a 900mA Constant Current Driver.
• Negative (-): Connect to the V- of the driver.
• Thermal: You MUST mount this 20mm plate onto a larger aluminum heatsink using thermal paste. Running this at 10W without a large heatsink will destroy the chip in seconds.

Frequently Asked Questions (FAQ)

1. Why does this LED have two different wavelengths?
   To cover a broader spectrum of UV-reactive materials that may require either 365nm or 395nm to activate.
2. Does it require a resistor?
   No, you should use a 900mA-1000mA Constant Current LED driver for stability.
3. Can I run this off a 12V battery?
   Only with a step-down constant current converter set to 10V/900mA.
4. What is the benefit of the white aluminum plate?
   It reflects stray light and provides the first layer of heat dissipation.
5. Is 365nm visible to the human eye?
   Very little. It will look like a faint "ghostly" white/blue glow, but it is actually very intense.
6. Will this cure 3D printer resin?
   Yes, it is ideal for DIY curing chambers for SLA/DLP prints.
7. Do I need thermal paste?
   Yes, between the 20mm plate and your main heatsink.
8. Can I dim this LED?
   Yes, if using a PWM-compatible constant current driver.
9. What is the lifespan?
   Approximately 50,000 hours if kept under 60°C.
10. Is the 365nm light dangerous?
    Yes, it is UVA. Prolonged exposure can cause skin and eye damage.
11. How do I know if it's 365nm?
    365nm causes much stronger fluorescence in many materials than 395nm.
12. What size lens fits this?
    Standard 20mm LED lenses/collimators.
13. Can I solder directly to the plate?
    Yes, there are designated (+) and (-) pads on the aluminum PCB.
14. Does it get hot?
    Extremely. 10W in such a small area requires active or large passive cooling.
15. Is it waterproof?
    No, the LED bead and solder points are exposed.
16. Can I use it for plant growth?
    UV is used in small amounts for specific terpene stress, but this is not a full-spectrum grow light.
17. What happens if I give it 12V directly?
    It will likely draw too much current and burn out instantly.
18. Why are there  small chips visible?
    High power LEDs are often arrays of smaller chips wired in series/parallel.
19. Does this work for gel nail polish?
    Yes, it will cure most UV gel polishes very rapidly.
20. Is this genuine 365nm?
    Yes, our Probots™ Lab Verified process ensures spectral accuracy.
