Cured in Seconds: The F3 3mm UV LED for Nail Curing & UV Adhesives
Ultraviolet light makes things happen that visible light never could — it hardens nail gel, sets UV glue, cures resin and reveals hidden marks. At the heart of these processes sits a compact, powerful emitter: the F3 3mm UV LED chip. This 3mm through-hole UVA LED delivers reliable 395–405nm output, making it a favorite for nail polish curing and a wide range of UV-driven applications.
What Makes This 3mm UV LED Stand Out
- 395–405nm UVA output — matched to the photo-initiators used in gels, glues and resins.
- Compact 3mm through-hole package — easy to mount in dense boards and small lamps.
- 3.0–3.6V forward voltage — simple to drive at a standard 20mA.
- Narrow 30° beam — concentrated UV energy exactly where you need it.
- Long lifespan — 50,000 hours of stable, consistent curing.
- RoHS/Reach compliant — safe, reliable and export-ready.

One UV LED, Many Application Scenarios
- Nail polish & gel curing — fast, even hardening for professional and home nail lamps.
- UV adhesive & glue curing — rapid bonding in electronics, optics and assembly lines.
- Resin & coating curing — setting 3D-printing resin, conformal coatings and inks.
- Fluorescence & counterfeit inspection — revealing security marks, UV inks and hidden defects.
- Specialty lighting — UV effects for art, stage and aquariums.
The Right UV Wavelength for the Job
This platform covers the popular UVA range, with 395nm and 405nm as standard options — 405nm cures slightly deeper into thick gels and resins, while 395nm is ideal for thinner coatings. Other UVA and UVC wavelengths are available to match your specific curing or disinfection requirement.
