Precision Ultraviolet Lighting for Makers and Technicians

Whether you are building a custom "black light" effect, repairing electronics, or experimenting with STEM projects, the quality of your components matters. Our 3mm 395nm UV LEDs are engineered to provide reliable, consistent ultraviolet output in a compact form factor.

Why Choose 395nm?

Unlike standard blue LEDs, these diodes emit light at the 395nm wavelength. This puts them right on the border of visible violet light and ultraviolet A (UVA). This specific wavelength is the "sweet spot" for many practical applications:

• UV Curing: Ideal for hardening UV-sensitive resins and glues used in jewelry making and electronics repair.
• Fluorescence: Makes UV-reactive paints, scorpions, and security strips on banknotes glow brightly.
• Sterilization Experiments: Useful for school science projects demonstrating the properties of light.

Easy to Integrate

Designed with standard 3mm water-clear casing (T-1 package), these LEDs fit easily into breadboards, PCBs, and custom housings. Their low power consumption and long operational life make them a superior choice for battery-operated devices.
