3mm Round Top Frosted UV/Purple LED (Pack of 20)

UV/Purple 3mm round top LED for blacklight effects and fluorescence activation. Specifications: - Package: 3mm radial through-hole (DIP) - Mount style: Through Hole (DIP) - Emission: True UV, 395-405nm wavelength - Forward voltage: 3.0-3.4V - Drive current: 20mA - Luminosity: 2,000-3,000 mcd - Viewing angle: Diffused - Lens color: Frosted / milky / white, not colored - Distinctive feature: compact 3mm size fits dense panel layouts and PCB designs This is a true UV emitter in the 395-405nm range, capable of activating fluorescent inks, dyes, and pigments. The frosted lens diffuses output for a wider, softer glow rather than a tight spot. Forward voltage of 3.0-3.4V at 20mA requires a series current-limiting resistor sized for the supply voltage. Applications: - Haunted house blacklight effects - Escape room puzzle clues revealed under UV - Theatrical UV and stage fluorescence activation

High-output 3mm LED for dense panels - 20 UV Purple 3mm through-hole LEDs that fit dense panel layouts and tight PCB designs — standard 2-pin radial form factor suitable for microcontroller projects, breadboard prototyping, instrument cluster indicators, and panel indicators Near-UV emission at 395-405nm - Emits true ultraviolet light at 395-405nm to excite fluorescent dyes, paints, and security inks. Forward voltage is 3.0-3.4V at 20mA drive current, with luminous output rated 2,000-3,000 mcd behind a frosted milky diffused lens for even spread. 3mm radial through-hole package - Compact 3mm round-top body fits dense panel layouts and tight PCB designs on standard 2.54mm pitch. Two-lead radial DIP format solders into through-hole boards or breadboards; frosted milky non-colored lens diffuses the 395-405nm output across a wide field. Polarity and resistor reference - Through-hole LEDs are polarity-sensitive: longer lead is anode (+), shorter lead is cathode (−). For 20mA drive current with a 3.0-3.4V LED, use a series resistor of 100Ω 1/4W on 5V, 300Ω 1/4W on 9V, 470Ω 1/4W on 12V, or 620Ω 1/2W on 15V. Blacklight and UV effect applications - True 395-405nm UV output powers haunted house blacklight scenes, escape room puzzle clues that glow only under UV, and theatrical UV stage effects. Activates fluorescent paint, dyes, and security inks for counterfeit detection in prop and maker builds.
