Product Information
Full details
This guide is for electronics hobbyists, makers, and professionals looking to integrate high-quality, warm white LED lighting into their projects. The key benefit is its powerful illumination and long lifespan, mounted on a convenient heatsink board. A primary caveat is the need for proper heat management due to its high power output. This product features EPISTAR or Bridgelux chips, a 120-degree viewing angle, and a lifespan exceeding 50,000 hours, all supplied on a 21mm diameter heatsink board.

FAQs
What is the typical lifespan of this LED?
The Switch Electronics 1W High Power LED has a rated lifespan of over 50,000 hours under optimal operating conditions.
Do I need a special power supply for this LED?
Yes, it requires a regulated DC power supply within the 3-3.6V range and a maximum current of 350mA. A constant current driver or a current-limiting resistor is highly recommended to prevent damage.
What does 'Warm White' (3000K) mean for this LED?
3000K indicates a color temperature that produces a yellowish, soft light, similar to incandescent bulbs, creating a comfortable and inviting atmosphere.
Is the included heatsink sufficient for all applications?
The included 21mm heatsink is suitable for moderate use. For continuous operation at maximum current or in enclosed spaces, additional heatsinking or active cooling may be necessary to prevent overheating.
Can I connect multiple LEDs in series or parallel?
In series, you would need a power supply with a higher voltage (e.g., for two LEDs, 6-7.2V) and a single current limiter. In parallel, each LED *must* have its own current limiter/driver, as LEDs can vary slightly and one could draw more current than others, leading to failure. Series connection is generally simpler if voltage allows.
What is the viewing angle and why is it important?
The 120-degree viewing angle means the light is spread out widely and evenly. This is useful for general illumination or backlighting, but less so for focused spotlight applications.
Are EPISTAR or Bridgelux chips better?
Both EPISTAR and Bridgelux are reputable manufacturers of LED chips known for their quality and reliability. The use of either indicates a high-quality component.
Troubleshooting
LED does not light up
Verify power supply voltage and polarity. Ensure the current is within the 350mA limit. Check solder connections for continuity and ensure they are not shorted.
LED flickers or dims significantly
This typically indicates a thermal issue. Ensure the heatsink is adequately attached and that the ambient temperature is not too high. If using a resistor, ensure it is appropriately rated and not overheating. Consider improving heat dissipation.
LED burns out quickly
The LED is likely being over-driven. Ensure the forward current does not exceed 350mA and the voltage is within the 3-3.6V range. Confirm that adequate heatsinking is in place to prevent overheating.
Inconsistent brightness between LEDs (in a multi-LED project)
Ensure each LED is receiving the same regulated current and voltage. Check for voltage drops across wires or connections, especially in longer runs. Use a constant current driver for best results.
Pros and Cons
Pros
- High brightness for its size
- Long operational lifespan
- Uses reputable LED chip brands (EPISTAR/Bridgelux)
- Comes mounted on a heatsink for easier thermal management
- Wide beam angle for diffuse lighting
- Consistent warm white color temperature
Cons
- Requires careful thermal management beyond the included heatsink for sustained high-power use
- Forward voltage and current must be regulated to prevent damage
- Not suitable for applications requiring directional, narrow beam light
- Pack size of 5 might be insufficient for large-scale projects
Setup, Compatibility & Care
Setup:
- Power Supply: Connect the LED to a regulated DC power supply that can provide a stable voltage between 3-3.6V and a current not exceeding 350mA. A current-limiting resistor or a constant current driver is highly recommended to protect the LED.
- Connections: Solder wires to the designated positive (+) and negative (-) pads on the heatsink board. Ensure good solder joints for reliable electrical contact.
- Thermal Management: While the LED comes mounted on a heatsink, for prolonged use at maximum current, consider mounting the entire heatsink board onto a larger metal surface or heat sink for enhanced heat dissipation.
Compatibility:
- This LED is compatible with standard electronics prototyping boards and breadboards when appropriate wiring is used.
- It can be integrated into projects controlled by microcontrollers (e.g., Arduino, Raspberry Pi) using appropriate driver circuits.
Care:
- Cleaning: Gently wipe the LED and heatsink with a dry, anti-static cloth. Avoid using liquids or abrasive cleaners.
- Environment: Operate within standard room temperatures. Avoid exposure to excessive moisture or corrosive environments.
- Inspection: Periodically check solder joints and wiring for any signs of wear or damage.
