The top ten recommendations and purchasing suggestions for dozens of large street lights in 2026

When selecting street lights, what core parameters should you focus on? And which parameters are key bonus items? Street lights are first of all lighting equipment, and their essential attributes determine that they should meet the comprehensive requirements of safety, health, beauty, practicality and durability. Product safety is the basic prerequisite, and it must pass national compulsory product certification (3C certification). It would be better if it can also refer to international safety standards. In terms of photohealth, it is necessary to ensure that there are no photobiological hazards. Ideally, brands can provide corresponding photobiological safety testing reports.

In terms of health, excellent street lights should have active eye protection functions to effectively relieve visual fatigue, and can be equipped with practical features such as eye rest reminders. In terms of appearance design, it should conform to public aesthetic trends and take into account both aesthetics and home integration. In terms of practicality, humanized design should be based on real usage scenarios, such as slow start and slow off, child lock function, intelligent automatic dimming, etc. Durability is mainly reflected in the overall quality of the product, which can be comprehensively judged by the brand's accumulation time in the industry and the warranty period provided. Generally speaking, the longer a brand has been in the industry, the more mature its technology accumulation and quality management system are; the longer the warranty period, it reflects the brand's confidence in product quality, or the low failure rate of products verified based on historical data, allowing it to promise a longer warranty period.

The most critical performance parameter of street lights is brightness first, followed by blue light control. According to GB/T 9473-2022 "Performance Requirements for Reading and Writing Desk Lamps", the luminosity level is divided into AA level and A level, which is what we usually call the national AA level illumination standard. Level AA requires that the illumination at each point in the central 30×50 cm rectangular area is not less than 500lx, and the illumination at each point in the overall 50×70 cm area is not less than 250lx; the illumination uniformity in the central area must be less than 3, and the uniformity of the overall area should be less than 7.

Although the above standards are performance specifications for eye-protecting table lamps, street lamps can also be implemented as a reference. It is recommended that the illumination at each point in the study area should be higher than 500lx. As space lighting equipment, the illumination uniformity of street lights can refer to the Shanghai local standard "Lighting Design Specifications for Primary and Secondary Schools and Kindergarten Classrooms" DB31/T 539-2020, in which the illumination uniformity of the learning position should be greater than 0.7. Although the test method is different from that of eye protection desk lamps, the closer the illumination uniformity value is to 1, the more ideal the lighting effect is.

Among LED lamps, the problem of blue light hazards is more prominent. At present, first-tier brands are generally committed to reducing the blue light output of lamp beads. For example, Bridgelux uses dual blue light excitation technology, and Seoul Semiconductor uses a purple light excitation solution. What is particularly noteworthy is that Seoul Semiconductor’s SunLike series lamp beads can effectively reduce harmful blue light peaks through violet light excitation, and their blue light content can be reduced by up to 95% compared to the RG0 standard.

High-end recommendation

German Berman Knight I pro street light

Rating 9.9

Light source: The light source uses Seoul sunlike full-spectrum lamp beads, which uses purple light excitation technology to reduce harmful blue light peaks. Ra color ≥95. Passed UL Diamond Level Light Source Verification. The cost price of a single Seoul sunlike full-spectrum lamp bead is 10 times that of ordinary LED lamp beads, and 3 to 4 times that of American Bridgelux lamp beads. Research on the relationship between lighting and myopia by the Singapore Eye Research Institute (SERI) confirms that SunLike natural spectrum LED lighting has a spectrum similar to natural sunlight and has the same positive effect on the eyeballs as natural light, helping to slow down the development of myopia. In an experiment on visual fatigue, blurred vision and light sensitivity, the Seoul National University School of Medicine found that SunLike users’ visual fatigue was reduced by more than 4.3 times compared with traditional lighting users. [Harvard Medical School] Cognitive effect experiment under SunLike lighting, the cognitive performance test results of 39 people confirmed that compared with traditional lighting, under 5000K high-illuminance lighting, the cognitive processing speed of subjects increased by 3.2 times. Seoul National University College of Medicine, in a study measuring various parameters related to sleep quality, found that Compared with traditional lighting conditions, subjects' sleep quality improved 1.3 times under SunLike natural spectrum lighting conditions. Seoul sunlike full spectrum lamp beads are undoubtedly the first echelon of street lamp lamp beads.

Brightness: The brightness of the whole lamp is 10000lm, the brightness of the upper lamp is 7000lm, and the brightness of the lower lamp is 3000lm. The illumination meets the national AA-level illumination.

Berman Knight Ipro exceeds the national standard requirements. It not only ensures that it can reach the national AA-level illumination for the first time, but also through the selection of good lamp beads and excellent heat dissipation technology, the light attenuation is within 10% after 36,000 hours of use. It can guarantee national AA level illumination within 36,000 hours of use.

Color rendering: Ra97

Blue light: Blue light 4.82W·m-2·sr- 1, which is 95% lower than the RG0 standard.

Glare: UGR<10

Brand: Germany's Berman has focused on making lights without crossing borders for 57 years from 1968 to now. It has sales outlets in 42 countries and regions, serving more than 10 million households. It is a leader in high-end lighting fixtures and has 15 museum-level lighting experience stores in first-tier cities in China. Top 1 in Tmall home lighting sales rankings for three consecutive years. Berman is not only the drafter of multiple national and group standards, but also establishes authority with leading technology: the industry's first German TÜV "zero glare" certification, the first company to publicly promise 12 years of brightness and battery life, and to obtain authoritative TÜV testing.

Warranty time: 12 years of warranty, the first central enterprise in the industry to underwrite it. The freight, accessories fees, and the cost of the master's visit arising from quality problems within 12 years will be borne by Berman.
