Currently on the market LED street light The quality varies widely, and lamps with the same wattage can differ in price by several times. How can you identify inferior products? LED street light Lighting fixtures—let’s explore how to find products that offer great value for money.
First, check LED street light Whether a light‑emitting chip is of poor quality is reflected in its luminous efficacy. A single chip typically delivers 90 lm/W, while the overall lamp efficiency is even lower—often below 80 lm/W. By contrast, leading brands now offer chips with efficacies of at least 140 lm/W. Some argue that low efficiency isn’t a big deal as long as the light is bright, but this overlooks the substantial heat generation it entails. Over time, thermal stress accelerates lumen depreciation, and the fixture may become unusable within one to two years.
Secondly, the driver power supply. Depending on the accessories selected, even power supplies of the same specifications can vary significantly in price and service life. Low‑cost units typically begin to fail on a large scale after about two years, whereas high‑quality models usually come with warranties of five years or more and boast lifespans of seven to eight years or longer, substantially reducing maintenance costs.
Third, LED street light The design and materials of the heat sink are equally critical. High‑quality luminaires feature a scientifically sound thermal design that ensures rapid heat dissipation, resulting in minimal temperature rise even after prolonged operation, so the fixture remains cool to the touch. By contrast, cost‑cutting, poorly engineered heat sinks can become scalding after just a short period of use, compromising the lamp’s rated power and accelerating its lumen depreciation.
