Three core indicators help you choose high-quality products

With the advancement of urban landscape lighting projects and the growth of demand for courtyard decoration, underground lamps, as lighting equipment that combines functionality and aesthetics, continue to gain popularity in the market. However, facing the dazzling array of underground lamp products on the market, how should consumers choose? Recently, reporters visited several lighting markets and consulted industry experts to bring you a professional guide to buying underground lamps.

"Underground lamps are buried underground for a long time, and the sturdiness and corrosion resistance of their materials are extremely high." A senior lighting procurement manager told reporters that high-quality underground lamp bodies are mostly made of high-purity aluminum alloy or stainless steel. Aluminum alloy materials have the characteristics of light weight and good heat dissipation. After anodizing or electrostatic spraying, the surface can effectively resist outdoor environmental erosion; while stainless steel materials are more durable and have excellent rust resistance. When purchasing, consumers can check the product material description or weigh the weight by hand to make a preliminary judgment. Underground lamps made of inferior materials are often light in weight, with rough surface treatment, and are prone to scratches and rust.

The light source is the core of the underground lamp, which directly affects the lighting effect and service life. At present, the mainstream underground lamps on the market mostly use LED light sources. "LED light sources have the advantages of energy saving, long life, high brightness, and good color rendering." Lighting engineer Wang Gong emphasized that when choosing, you should pay attention to the color temperature of the light source. Warm white temperature (2700K - 3500K) creates a warm atmosphere and is suitable for courtyards and gardens; white temperature (4000K - 5000K) is bright and clear, suitable for public areas such as squares and roads. At the same time, you should check the luminous flux and color rendering index (Ra) of the light source. The higher the luminous flux, the higher the brightness, the closer the color rendering index is to 100, and the better the color reproduction. The color rendering index of high-quality underground lamps is generally above 80.

Due to the special working environment of underground lamps, waterproof performance is very important. "Underground lights that do not meet the waterproof rating are very likely to be damaged by short circuits due to water ingress." Industry experts remind that the waterproof rating of underground lights must reach IP67 or above, where "IP" is the international code used to identify the protection level, "6" means that it is completely protected from foreign objects and dust, and "7" means that it can be immersed in water for a short time without any damage under a certain pressure. When purchasing, consumers can ask merchants to provide product waterproof test reports to ensure product quality. In addition, attention should also be paid to the heat dissipation design of underground lights. A good heat dissipation structure can effectively extend the service life of the lamp. Designs such as fin heat dissipation and thermal conductive silicone heat dissipation are relatively common and practical.

As the application scenarios of underground lights continue to expand, consumers can not only pay attention to the above core indicators when selecting, but also choose products with functions such as intelligent dimming and remote control according to actual needs. Industry insiders predict that in the future, underground lights with high performance and intelligence will become the mainstream of the market, bringing more possibilities for urban night scenes and home decoration.
