As solar energy becomes more popular, an increasing number of people are starting to purchase solar streetlight products, leading to a rapid expansion of the solar streetlight market. However, at the same time, the prices of solar streetlights vary widely, leaving consumers confused and unsure. Therefore, when purchasing solar streetlights, it is important to be aware of potential traps set by manufacturers, which can be presented in the following aspects:
1. Low-end chips. The core component of LED lighting is the chip, which directly determines the performance of the light! However, some unscrupulous manufacturers take advantage of customers’ lack of expertise and use low-cost chips to provide low-quality products at a high price, resulting in direct financial losses and serious quality risks for the LED lights.
2. High specs, low configuration. Unscrupulous manufacturers often misrepresent parameters such as power ratings and thickness of light poles. Reductions in configuration are often difficult for customers to detect under normal circumstances. This is a primary method used by unscrupulous manufacturers to lower prices and disrupt the market.
3. Poor heat dissipation design. For LED chips, for every 10 degrees of increase in junction temperature, the lifespan of semiconductor devices decreases exponentially. Therefore, heat dissipation is a critical factor in ensuring the lifespan and quality of LED streetlights. Unscrupulous manufacturers often skimp on materials in this area to cut costs, and this harm is not immediately detectable but becomes apparent after some time of use.
4. Chip brand and quality. The quality of the LED chip directly influences the performance and price of the light! Some unscrupulous vendors exploit customers’ lack of expertise by passing off low-quality chips from small manufacturers as premium brands, or using lower-grade chips from the same manufacturer as high-quality ones, such as copper wire connections masquerading as gold wire connections, deceiving consumers and causing them to pay a premium for substandard products.
5. Poor heat dissipation design. In terms of heat dissipation design, with the high brightness requirements for LED solar streetlights and harsh usage environments, inadequate heat management can quickly lead to LED aging and decreased stability.
6. Power supply quality. The price and quality of the power supply are closely related to the design and choice of internal electrical components. It’s not sufficient for the light to simply turn on, as low-quality substitutes are prevalent in this area.
7. Excessive harmful substances in the light source. The darkening of LED light sources is a common issue faced by many LED companies, mainly due to the presence of materials that significantly affect the lifespan of the light source.
8. Confusion of concepts. For example, solar LED streetlights generally allow for adjustable power usage, but some manufacturers mislead consumers by only mentioning illumination time without discussing power usage, taking advantage of customers’ lack of understanding.
9. Sacrificing scientific design of light distribution systems to cut costs. Unscrupulous manufacturers may alter or even eliminate distribution systems to save costs, seriously affecting lighting effectiveness and leading to issues like uneven illumination and shadows beneath lights. Such problems are usually difficult to detect without professional testing.
10. Misleading specifications. The surge in popularity of solar streetlights has come alongside declining profit margins and has led to fierce competition. As a result, many manufacturers may resort to skimping on quality and misrepresenting product parameters, including wattage of light sources, wattage of solar panels, battery capacity, and even the materials used for light poles. This issue is somewhat tied to customers’ tendency to compare prices and insist on lower costs, along with some manufacturers’ dubious practices.
11. Copper wire masquerading as gold wire and issues with controllers. Many LED manufacturers attempt to use alternatives like copper alloys or silver-coated wires in place of expensive gold wires. While these alternatives may excel in certain characteristics, they significantly falter in terms of chemical stability—e.g., silver wires are prone to sulfide/chloride/bromide corrosion, and copper wires easily oxidize. For packaging silicone that is similar to water-absorbing and breathable sponge materials, these replacements increase the risk of chemical corrosion to bonding wires, diminishing the reliability of the light source, leading to increased failure rates over time. In the case of solar streetlight controllers, faults can result in complete lights going out, delayed on/off functioning, partial failures, individual LED lights going out, and flickering lights.
This concludes our discussion on potential pitfalls when purchasing solar streetlights. Homogeneous competition inevitably leads to price wars, which makes it difficult to avoid the sales tricks employed by unscrupulous manufacturers that harm consumers. Therefore, one must be cautious of these traps when making a purchase.
