The Timeless Workhorse: 5mm Round Top LED
Decades after the first light-emitting diodes appeared, the 5mm round top LED remains one of the most widely used light sources in electronics. Its classic dome lens, through-hole leads and broad color range make it the go-to choice for indicator lights, display panels and countless DIY and industrial projects. Dongguan Lanjin Optoelectronics Co., Ltd. supplies high-quality 5mm LED diode lights in white, red, green, blue, yellow, amber and orange.
Why the 5mm Round Top LED Stands Out
- Dome (round top) lens focuses light into a bright, clearly visible beam.
- Seven color options: white, red, green, blue, yellow, amber and orange for vivid, color-rich designs.
- Low 20 mA current with a 50,000-hour rated lifespan.
- Through-hole leads for easy hand soldering and prototyping.
- RoHS / REACH compliant, built on San'an and Epistar chips.

Choosing the right 5mm LED diode lights is simple: match the wavelength to the job — red for alarms and warning indicators, green for power-on status, blue for modern accent lighting, and white for general illumination. Lanjin can also match specific brightness bins, lens finishes and lead configurations to meet custom production requirements.
Top Application Scenarios
- Indicator and status lights: power, signal and alarm LEDs on appliances, chargers and industrial equipment.
- Digital displays and scoreboards: bright, focused dots that stay readable at a distance.
- Panel backlighting and switches: compact illumination for control panels and dashboards.
- Automotive and signal lighting: reliable single-diode indicators for vehicles and traffic systems.
- Signage and advertising: multi-color arrays for channel letters and light boxes.
- DIY, Arduino and education: the classic through-hole LED for makers and STEM projects.
