Hello everyone. The world of LEDs is vast and, unfortunately, rife with counterfeits. This article delves into the pervasive problem of fake CREE LEDs, addressing common concerns and providing practical advice on how to distinguish genuine CREE products from their imitations. The proliferation of counterfeit LEDs, particularly those bearing the CREE brand name, presents a significant challenge for consumers and businesses alike. This is a complex issue with implications for performance, safety, and the overall LED market.
How to Distinguish Real CREE LEDs or Fake?
Identifying genuine CREE LEDs requires a multi-pronged approach. There's no single foolproof method, but a combination of techniques significantly increases your chances of spotting a fake.
* Packaging and Markings: Genuine CREE LEDs come in carefully designed packaging, often with security features. Look for clear, high-quality printing, including the CREE logo and part number. Counterfeit packaging is often poorly printed, with blurry images and inconsistencies in font styles. The markings on the LED itself are crucial. Real CREE LEDs will have the manufacturer's markings clearly and precisely etched or printed. Look for inconsistencies in the font, spacing, or depth of the markings. Blurry, uneven, or poorly aligned markings are strong indicators of a counterfeit.
* Physical Inspection: Examine the LED's physical construction. Genuine CREE LEDs are generally built to high tolerances. Look for inconsistencies in the shape, size, or color of the LED die. Poor solder joints, uneven epoxy dome application, or visible imperfections in the lens are common signs of a counterfeit. Compare the physical characteristics of your LED to images of genuine CREE LEDs found on the official CREE website or reputable distributors.
* Electrical Characteristics: This is arguably the most reliable method, but requires specialized equipment. Using a multimeter, you can measure the forward voltage (Vf) and the luminous flux (lumens) of the LED. These values should align closely with the specifications provided by CREE for the specific LED model. Significant deviations suggest a counterfeit. Furthermore, you can measure the spectral output using a spectrometer to compare it to the manufacturer's specifications. This method is more technically demanding but offers a more definitive result.
* Supplier Reputation: Purchase from reputable suppliers. Avoid suspiciously cheap deals on online marketplaces like eBay, especially from sellers with poor feedback ratings or limited history. Stick to authorized CREE distributors or well-established electronics suppliers. Check for seller certifications and warranties.
* Documentation and Traceability: Genuine CREE LEDs often come with documentation or certificates of authenticity. If you're purchasing in bulk, request these documents. The ability to trace the origin of the LEDs is crucial in verifying their authenticity.
How Do You Know If Your LED Lights Have Cree LED?
This is trickier than simply identifying individual LEDs. Many manufacturers use CREE LEDs in their lighting products, but the entire assembly isn't necessarily a CREE product. Look for clear labeling on the fixture itself. Reputable manufacturers will usually specify the LED type used. However, even with this labeling, there's still a risk of counterfeits being used in the assembly process. If you suspect counterfeits, consider the points mentioned above to inspect the individual LEDs within the fixture.
