LEDs have become a hot topic in the lighting industry recently. With their increasing use in urban night lighting and building illumination, it's essential for consumers to stay informed and make smart choices. While the market is booming, not all LED products are created equal. Here’s a closer look at some key factors that determine the quality and price of LEDs:
1. Brightness varies significantly among LEDs, which directly affects their cost. For safety, LED luminaires should meet the IEC Class I standard.
2. Anti-static capability plays a major role in an LED’s lifespan. LEDs with higher static resistance—usually over 700V—are more durable and thus more expensive.
3. Color consistency is crucial. LEDs with the same wavelength produce the same color, and those with precise color matching tend to be pricier. Manufacturers without spectrophotometers often struggle to achieve pure colors.
4. Leakage current refers to reverse current flow, which can damage LEDs. High leakage current shortens the lifespan and lowers the price of the product.
5. The angle of illumination affects both performance and cost. Specialized angles, like full diffusion, come at a premium.
6. Lifespan is determined by light decay. LEDs with lower decay rates last longer and are generally more expensive.
7. The quality of the wafer used in LEDs also impacts the price. Japanese and American chips are typically more costly, while those from Taiwan and China are more affordable.
8. Larger wafers tend to offer better performance, and the price increases with the size of the wafer.
9. The type of encapsulation material matters. Ordinary epoxy resin is common, but UV-resistant and fire-retardant materials are more expensive and ideal for outdoor use.
Each LED product is designed for specific applications. Reliable LED lighting must consider multiple safety aspects, including electrical, fire, environmental, mechanical, health, and usage safety. From an electrical safety standpoint, compliance with international and national standards is essential.
Although LED technology is still evolving, China’s national standards may lag behind global ones. However, products that undergo rigorous testing and carry certifications like GS, CE, or UL are more reliable and usually cost more. Consumers should pay attention to the authenticity of these certifications, as only a few manufacturers hold them.
From a health perspective, non-toxic materials increase the cost, especially for indoor lighting. Avoid cheap LEDs that emit strong odors. Only a few manufacturers use safe, non-toxic materials, so you can often tell by smell—smelly products are usually cheaper. Toxins like lead, mercury, and cadmium require lab analysis.
Finally, environmental safety features such as dustproofing, moisture resistance, UV protection, and low-temperature stability add to the cost. These features ensure long-term reliability and performance in various conditions.
