When purchasing solar LED street lights, be cautious not to fall for low prices. The price of solar street lights is always a concern for buyers, as everyone hopes to spend less for street light products, but often the reality is contrary. Market prices reflect value; you get what you pay for.
For instance, a 7-meter high street light with a 40-watt LED light source can vary significantly in market price. One manufacturer may quote 1100, while another might quote 1800, leaving a huge disparity. Where does this difference come from? The components of a street light are primarily the lamp pole and the light head. The lamp pole material is steel, and its quality can be assessed as either thin or thick, which doesn’t involve much technical complexity and won’t affect later use. Thus, after discussing the lamp pole, we are left with the light head. Can such a small component cause such a significant overall price difference? Absolutely, it can.
LED lighting fixtures are high-tech green energy products that involve several components, including LED chips, aluminum substrates, lamp shells, and constant current drivers. Among these components, two key elements are the LED chips and constant current drivers.
LED Chips: LED chips are highly technical products, which can be divided into two parts: the chip and the package. Well-known LED chip brands globally include the GE-produced CREE (which is very expensive), while domestic options include brands like Epistar and Bridgelux. Numerous second and third-tier brands exist that are not worth mentioning. Compared to foreign brands, domestic brands tend to have lower quality but are priced more affordably, catering to Chinese consumer spending power. Although choosing a good chip is crucial, a better chip doesn’t always equate to higher quality, as it also involves the packaging process. Packaging simply refers to encasing the LED chip in a special material to protect it from water and gas. This requires using highly transparent materials for encapsulation. The quality of encapsulation directly affects the performance and lifespan of the LED light source.
Constant Current Driver: Even with good chips and excellent packaging techniques, the performance cannot be guaranteed without a constant current driver, as ordinary street lights require this driver to operate the light source. The constant current driver regulates current and voltage, ensuring that the light source functions continuously. However, poor-quality constant current drivers cannot achieve this consistently, meaning they might work sometimes and fail at others. Unstable LED light sources subjected to prolonged instability will face serious lumen depreciation, shortening their lifespan. A quality constant current driver can cost over twice that of a generic one, which is a major reason for their limited application.
The primary factor leading to the significant price variation of street lights is the LED light head. High-quality branded light heads have superior components and manufacturing processes. It’s easy to see the difference in appearance when comparing poor-quality light heads. To buy high-quality street lights, be cautious and avoid falling into the trap of low prices, or else you may end up losing more than you gain. If you are looking for reliable rural solar street lights and trustworthy solar street light manufacturers with reasonable LED solar street light prices, consider direct purchases from manufacturers for dependable quality!
