A 2835 1W 3V 350mA LED is a high-power Surface Mount Device (SMD) LED commonly used in commercial lighting, industrial fixtures, flood lights, high-bay lights, grow lights, and customized LED modules. Compared with standard 0.2W or 0.5W 2835 LEDs, the 1W version delivers significantly higher brightness while maintaining the compact 2.8 × 3.5 mm package.

Applications
A 2835 1W 3V 350mA LED is widely used in:
LED street lighting
Flood lights
High bay lighting
Warehouse lighting
Commercial luminaires
Solar street lights
Horticulture grow lights
Industrial lighting
Tunnel lighting
LED modules
Architectural lighting
Driver Recommendation
Since the LED operates at 350mA constant current, it should be driven with a constant-current LED driver rather than a constant-voltage power supply.
Typical driver configuration:
Output Current: 350mA
Output Voltage:
1 LED: 3V
5 LEDs in series: 15V
10 LEDs in series: 30V
12 LEDs in series: 36V
Thermal Design
Although rated at only 1W, proper heat dissipation is important.
Recommended practices:
Mount on an aluminum MCPCB.
Use a thermal interface material between the PCB and heatsink.
Keep junction temperature below 85°C for maximum lifespan.
Ensure adequate airflow in enclosed fixtures.
Advantages over Lower-Power 2835 LEDs
| Feature | 0.2W | 0.5W | 1W |
|---|---|---|---|
| Current | 60mA | 150mA | 350mA |
| Power | 0.2W | 0.5W | 1W |
| Brightness | Low | Medium | High |
| Thermal Requirement | Low | Medium | Higher |
| Commercial Lighting | Limited | Good | Excellent |
| Outdoor Lighting | Rare | Common | Widely Used |
Summary
The 2835 1W 3V 350mA LED offers an excellent balance of compact size, high brightness, and energy efficiency. With a typical forward voltage of 3V, a drive current of 350mA, and luminous efficacy reaching 150–200 lm/W, it is a popular choice for professional LED lighting applications such as street lights, flood lights, high-bay fixtures, horticultural lighting, and custom LED modules where reliable performance and long service life are essential.
