Description / 0603 SMD UV / Purple - Ultra Bright LED

The 0603 UV Purple SMD LED (1.6 × 0.8mm, metric 1608) is the most widely used SMD indicator size in both hobbyist and production PCB work — small enough for tight layouts, large enough to hand-solder reliably with flux and a fine-tip iron. UV/Purple output creates blacklight effects — used in art, cosplay props, escape room builds, and decorative accent lighting.

Package0603 (1608 metric) — SMD surface mount
Forward Voltage3.0-3.6v
Brightness25mcd
Viewing Angle120 Degrees
LensClear
Drive Current20mA typical

Hand-solderable with a fine-tip iron and flux paste. Easier than 0402, still small enough for tight decoder and PCB layouts.

Common uses:

  • Gaming console repair — Xbox 360/One, PS3/PS4, Wii, and Game Boy indicator LED replacement (iFixit community)
  • Guitar pedal builds — Boss 2017+ models and modern stompbox PCBs use 0603 indicator LEDs (Freestompboxes, PedalPCB)
  • Mechanical keyboard backlight repair — per-key indicator LEDs on custom PCBs (r/MechanicalKeyboards, Geekhack)
  • N scale and HO scale DCC decoder lighting — headlights, interior lights, and function outputs
  • Custom PCB indicators for ESP32/RP2040 projects, breakout boards, and open-source hardware designs

*Use 15V instead of 12V for vehicle/alternator sources to account for charging voltage (13.8–14.4V).

DC power recommended: LEDs are designed for DC. Running on AC will cause flickering and reduce lifespan. If you're using a low-voltage AC source — such as a model railroad transformer output or DCC track voltage — convert it to DC first with a bridge rectifier.

Also available: 0402 (smaller) · 0805 (larger)

Sold individually (1 LED per quantity ordered).

About true UV LEDs: This LED emits genuine ultraviolet light at 395–405nm. To the human eye, true UV often appears as a deep blue or blue-violet hue rather than a vivid purple — this is normal and expected. The perceived color can change depending on what the UV light is shining on (fluorescent materials will glow brightly) and the ambient lighting in the room. In a dark room, the LED looks blue-violet; in a lit room it may appear dimmer than other 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 visibly bright purple without UV properties, see our diffused purple LEDs.

Extremely small. No description on size. Just industry model # so if you don’t know, don’t be like me and do your research on industry sizes. Not sellers fault. Good buying experience. Would buy from again after doing my due diligence on model #’s and sizes.
