When it comes to resin curing, UV lights are an essential tool for achieving precise and durable results. However, not all UV lights are the same. Two common wavelengths used in UV lights are 365nm and 395nm, each with its own advantages and limitations. This guide dives deep into the differences between 365nm and 395nm UV lights, helping you determine the best choice for your resin curing projects.
Understanding UV Light and Resin Curing
UV light plays a key role in curing resin by initiating a photochemical reaction that hardens the material. The effectiveness of this process largely depends on the wavelength of the UV light used.
- 365nm UV light: Falls in the UVA spectrum, producing deeper and more precise curing.
- 395nm UV light: Also in the UVA spectrum but closer to visible light, offering slightly broader usability but less depth in curing.
Both wavelengths can cure resin, but choosing the right one depends on your project’s requirements.
Key Differences Between 365nm and 395nm UV Lights
| Feature | 365nm UV Light | 395nm UV Light |
|---|---|---|
| Wavelength | 365 nanometers | 395 nanometers |
| Curing Depth | Deeper curing, ideal for thicker resins | Shallower curing, better for surface layers |
| Resin Compatibility | Works with most UV-curable resins | Works with resins less sensitive to UV light |
| Light Visibility | Low visibility (less visible to the naked eye) | High visibility (purple hue to the naked eye) |
| Heat Generation | Minimal heat during operation | Generates more heat |
| Power Consumption | Slightly higher due to precision | Lower power consumption |
| Applications | Professional-grade applications | General-purpose and hobbyist use |
| Cost | Typically more expensive | More affordable |
Benefits of 365nm UV Lights for Resin Curing
- High Precision: The shorter wavelength ensures more accurate and uniform curing, even in thicker resin layers.
- Deeper Penetration: Suitable for high-quality or professional resin projects.
- Minimal Yellowing: Prevents discoloration in clear resins, ensuring a clean finish.

Benefits of 395nm UV Lights for Resin Curing
- Budget-Friendly: More affordable and widely available.
- Visible Light: Easier to see where the UV light is being applied.
- Good for Surface Curing: Works well for thin resin layers or quick fixes.
Choosing the Right UV Light for Your Project
When deciding between 365nm and 395nm UV lights, consider the following factors:
- Project Type: For professional applications or intricate designs, opt for a 365nm UV light. For general crafting or hobby projects, a 395nm UV light may suffice.
- Resin Thickness: Thicker resins benefit from the deeper penetration of 365nm UV lights.
- Budget: 395nm UV lights are a more economical choice for beginners or occasional use.
Practical Tips for Using UV Lights in Resin Curing
- Work in a Dark Environment: This minimizes interference from ambient light, ensuring optimal curing.
- Maintain Proper Distance: Keep the UV flashlight 2–5 inches from the resin surface for best results.
- Curing Time: Follow the resin manufacturer’s guidelines for exposure time, adjusting based on the UV light wavelength.
- Safety Precautions: Always wear UV-blocking glasses to protect your eyes from prolonged exposure.
Conclusion
Both 365nm and 395nm UV lights have their place in resin curing, but the best choice depends on your specific needs. If you’re aiming for professional-grade results or working with thicker resin layers, a 365nm UV light like the Tank007 AA02 is the ideal option. For general-purpose applications or budget-friendly solutions, 395nm UV lights can be effective.
By understanding the specifications and benefits of each wavelength, you can make an informed decision and achieve the best possible results in your resin curing projects. For premium-quality UV flashlights, explore our range at Tank007.
