• Forward Voltage (Vf): 32.0V - 36.0V DC
• Forward Current (If): 3000mA - 3500mA
• Radiant Power: Extreme High-Density Output
  
• Viewing Angle: 120 - 140 Degrees
• Chip Structure: 100-Die Matrix (10 Series / 10 Parallel)
• Substrate: Heavy-Duty Red Copper (Required for 100W)

Key Applications & Projects

• Large-Scale Resin Curing: Curing entire batches of SLA prints or large industrial castings in seconds.
• Non-Destructive Testing (NDT): Illuminating entire engine blocks or aircraft parts for magnetic particle inspection.
• Photochemical Reactors: Driving high-volume chemical synthesis requiring intense UVA activation.
• Forensic Search: Crime scene floodlighting to detect biological fluids over large areas.
• Aquarium Lighting: (Expert Only) Actinic "Super Actinic" supplementation for deep-water coral simulation.

Project Evolution 

• Past Projects (Prerequisites): You have likely pushed 30W or 50W LEDs to their limit and found they lack the range or intensity for commercial throughput.
• Feature Upgrade: This 100W monster provides Area Saturation. Instead of spot-curing, you can flood an entire workstation with high-intensity UV, dramatically increasing process efficiency.
• Effort Level: Industrial/Expert. Requires massive active cooling (CPU cooler or water cooling) and a specialized 100W LED driver.

Virtual Technician & Wiring

• INDUSTRIAL HAZARD WARNING: This device emits dangerously high levels of UVA radiation. IMMEDIATE EYE DAMAGE can occur. Never look at the emitter. Full skin coverage and UV-rated face shields are mandatory.

   

• Thermal Management: CRITICAL: A standard heatsink will result in failure in <2 seconds. You MUST use a high-end CPU cooler (rated for 150W TDP) or a water-cooling block.

• Driving: Probots™ Logic-Safe ⚡ Rule: Use a dedicated 100W Constant Current Driver (3000mA-3500mA). Do not attempt to drive this with simple voltage sources.

Wiring:

• Positive (+): Marked + (Wider Tab). Use heavy-gauge wire (18AWG+).
• Negative (-): Marked - (Narrower Tab).

Wiring:

• Positive (+): Indicated by the + sign or wider solder pad.
• Negative (-): Indicated by the - sign or narrower solder pad.

Frequently Asked Questions (FAQ)

1. What is the real power draw?
   It draws roughly 100-110 Watts at full load (approx. 34V @ 3.2A).
2. Can I use a 12V battery?
   No. You need a high-power (150W+) Boost Converter to step up 12V to roughly 34V.
3. How fast will it overheat?
   Instantly. Without a massive heatsink, the core will melt in roughly 1 second.
4. Do I need water cooling?
   While a high-end air cooler works, water cooling is highly recommended for continuous industrial operation.
5. Is 380nm dangerous?
   Yes. At 100W, the reflected light alone is enough to cause "welder's flash" (corneal burn). Use professional protection.
6. Can I use a resistor?
   Absolutely not. The current is too high (3.5A). A resistor would burn up. Use a Constant Current Driver.
7. Is it waterproof?
   No. The COB surface is exposed and must be protected from moisture.
8. Does it emit visible light?
   Yes, a very bright purple glow, but the invisible UV energy is 20x stronger.
9. Can I dim it?
   Yes, with a 100W driver that supports PWM/Analog dimming.
10. What is the lifespan?
    50,000 hours, BUT only if the temperature is kept below 60°C. This is difficult to achieve at 100W without excellent cooling.
11. Will it bleach materials?
    Yes. It will rapidly degrade plastics, bleach fabrics, and yellow paper.
12. Can I solder wires directly?
    It is difficult because the large copper base sucks heat away. A high-wattage soldering iron is needed.
13. Why 380nm and not 365nm?
    380nm is more efficient to produce at 100W power levels and offers deeper penetration for thick curing.
14. Is it compatible with Arduino?
    No. You need a massive external driver and MOSFET to control it via Arduino.
15. Does it come with thermal paste?
    No. You must buy high-performance thermal grease (like Arctic Silver).
16. How much current does it need?
    3000mA is the "sweet spot" for balancing lifespan vs brightness. Max is 3500mA.
17. Can I use it for stage lighting?
    Only for specialized UV effects, and never pointed directly at the audience.
18. Is it Probots™ Secure-Transit  protected?
    Yes, packed in a rigid box with anti-static foam.
19. How many dies are inside?
    It uses a 100-die matrix (10 Series, 10 Parallel) of 1W chips.
20. Can I look at it with sunglasses?
    NO. Standard sunglasses are useless against this intensity. Use ANSI Z87.1 rated industrial UV face shields.
