Description / 5mm Round Top UV / Purple LED - Ultra Bright
The 5mm UV Purple LED (Round Top, Clear) is the standard through-hole LED for true UV/blacklight effects (395-405nm), fluorescent material activation, escape room UV clues, mineral inspection. Clear lens with a focused 20-30 Degrees beam — bright and directional, the classic DIP LED that fits every breadboard, panel bezel, and holder on the market.
The 5mm (T-1¾) is the most popular LED size in the world — the standard for breadboard prototyping, hobby projects, panel indicators, and every electronics starter kit. Fits all 5mm holders and bezels.
Important UV note: True UV LEDs (like this one) emit ultraviolet light at 395–405nm, which often appears as a deep blue or violet hue to the human eye rather than a vivid purple. This is normal and expected — real UV light is at the edge of visible perception. The perceived color can change depending on what the light is shining on (fluorescent materials will glow brightly) and the ambient lighting in the room. In a dark room, the LED itself will look blue-violet; in a lit room, it may appear dimmer than other LED colors because most of the output is in the invisible UV spectrum. True UV LEDs also have lower visible light intensity than other colors — this is inherent to the wavelength, not a defect. If you want a vivid, visibly bright purple without UV properties, see our diffused purple LEDs instead.

Common applications
- True UV blacklight effects: Activates fluorescent paints, inks, and fabrics for haunted houses, escape rooms, and stage productions. This is a genuine UV LED outputting at 395–405nm.
- Escape room puzzles: Hidden UV-reactive messages, invisible ink clues, glowing artifact props.
- Cosplay glow effects: UV-reactive costume elements that glow under blacklight at conventions.
- Mineral and currency inspection: UV LEDs reveal fluorescent minerals and security features on banknotes.
- Resin curing: Some UV-cure resins respond to 395–405nm LEDs for hobby-scale curing.
Standard T-1 3/4 through-hole footprint. Fits all 5mm LED holders, bezels, and panel-mount clips. Add a current-limiting resistor matched to your supply voltage — see our LED Resistor Calculator for the exact value.
Need a wider beam? See our 5mm Diffused Round Top LEDs (soft glow, no hotspot) or 5mm Straw Hat LEDs (120–140° wide angle).
