Product Details
✓5mm through-hole LED for projects and panel indicators - 20 UV Purple 5mm through-hole LEDs in industry-standard form factor that fit standard 5mm LED holders, bezels, and panel cutouts — suitable for microcontroller projects, panel indicators, gauge cluster work, and electronics prototyping
✓True UV emission at 395-405nm - 5mm round-top LED emits ultraviolet at 395-405nm with 1,000-1,500 mcd output, 3.0-3.4V forward voltage at 20mA drive current. Diffused lens in emitting color provides wide even glow ideal for activating fluorescent pigments, inks, and dyes.
✓Standard 5mm radial through-hole package - 5mm DIP form factor fits standard LED holders, bezels, and panel clips on 2.54mm pitch breadboards or perfboard. Two long radial leads accept solder, screw terminals, or crimp connectors. Industry-standard footprint drops into existing 5mm sockets without modification.
✓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.
✓UV blacklight hobby applications - 395-405nm output activates fluorescent paints, glow pigments, and security inks for haunted house blacklight scenes, escape room puzzle clues and hidden-message reveals, theatrical UV stage effects, costume accents, and counterfeit currency or document inspection.
