The 5050 SMD LED — named for its 5.0 mm × 5.0 mm surface-mount package — is one of the most versatile LED formats in the global lighting industry. Significantly larger than 3528 and 2835 packages, the 5050 delivers substantially higher luminous output while supporting multi-chip configurations for RGB color mixing, tunable white, and dedicated high-power single-color applications.
| Parameter | Typical Specification |

| Luminous Flux (White) | 18–28 lm per LED (at 60 mA) |
| Viewing Angle | 120° |
| Forward Voltage | 3.0–3.4 V (white); 2.0–2.2 V (red), 3.0–3.4 V (green/blue) |
| Forward Current | 60 mA per chip (180 mA total for RGB) |
| Color Temperature | 2700 K – 6500 K |
| CRI | ≥ 80 (standard), ≥ 90 (high-CRI variants) |
| Lifetime (L70) | ≥ 50,000 hours |
Higher Power Handling: The larger thermal pad enables sustained operation at up to 60 mA per chip — triple the current of typical 3528 LEDs — delivering significantly higher brightness per component.
Triple-Chip RGB Integration: The 5050 is the de facto standard for RGB LED strips, housing independent red, green, and blue chips in a single package for full-spectrum color mixing.
2–3× Brighter than 3528: At equivalent drive currents, a 5050 LED produces two to three times the luminous flux, reducing component count and simplifying PCB layouts.
Proven Field Reliability: With billions of units deployed globally, the 5050 platform offers mature manufacturing processes and extensive real-world reliability data.
The 5050 SMD LED dominates the global LED strip market with applications including:
RGB and RGBW flexible strips — full-color accent lighting for residential, hospitality, and retail
Single-color high-output strips — task lighting, under-cabinet, and cove illumination
Addressable digital strips — pixel-mapped installations with individual LED control for dynamic effects
Waterproof IP65/IP67/IP68 strips — outdoor facade, landscape, and pool lighting
Channel letter and sign cabinet backlighting
Linear pendant and recessed luminaires for office and retail
Wall-washing and facade grazing fixtures
Staircase, handrail, and pathway safety illumination
Daytime running lights and auxiliary accent lighting
Interior ambient and footwell illumination
Marine navigation and deck lighting
RV and caravan lighting systems
Backlit channel letters and dimensional signs
Lightbox panels for retail and trade show displays
Edge-lit acrylic signage requiring high uniformity
Thermal Management: Use aluminum-core PCBs or adequate copper pour areas, especially for high-density strip designs operating near maximum rated current.
Constant-Current Driving: For white and single-color applications, constant-current drivers ensure stable brightness. For RGB strips, PWM-controlled constant-voltage schemes are standard.
SMT Compatibility: The 5050 package is fully compatible with standard pick-and-place assembly. Ensure MSL 3 or better packaging and follow baking procedures if floor-life limits are exceeded.
Optics and Diffusion: The 120° Lambertian pattern suits general illumination; add secondary optics or diffusers for narrower beams or uniform surface luminance.
ESD Protection: Observe proper ESD handling. RGB variants typically include built-in protection diodes; single-chip white versions may need external protection.
Smart Lighting: 5050 RGB/RGBW LEDs with integrated IC drivers enable Wi-Fi, Bluetooth mesh, and Zigbee-connected ecosystems for residential and commercial IoT.
High-CRI Demand: 90+ CRI white LEDs are growing in retail, museum, and healthcare settings where color accuracy is critical.
Tunable White: Dual-white 5050 packages combining warm and cool chips enable dynamic circadian lighting for offices and healthcare facilities.
Cost Competitiveness: Mature manufacturing scale continues driving cost reductions, making 5050 solutions increasingly competitive against traditional lighting technologies.
