LED Application Scenarios: Why Through-Hole LEDs Still Win the Job
Surface-mount may dominate the headlines, but through-hole LEDs remain the backbone of displays, appliances and stage fixtures — anywhere a rugged, bright, easily hand-mounted lamp is needed. In this article we spotlight one concrete through-hole model and show how Lanjin supports global buyers as a full-range China through hole led distributor.
Featured Model: 5 × 4 × 6 mm Oval Through Hole LED
The 5 × 4 × 6 mm oval through-hole LED is a diffused 546-style lamp built for display screens and status lighting. Its tall oval lens produces a wide, even beam across red, green, blue, yellow-green, yellow, orange and white — all driven at just 20 mA. Well-known brand chips and gold-wire bonding keep brightness consistent from batch to batch.
