what customers care about when they buy led lights?

1. Product quality
Brightness and luminous flux
Brightness is a point of great concern to customers. For different usage scenarios, such as indoor lighting, outdoor street lights, commercial display lighting, etc., the required brightness is different. Luminous flux is measured in lumens (lm), which represents the total amount of visible light emitted by a light source. For example, for LED desk lamps used for reading, the luminous flux is generally between 300-700lm, which is more suitable; while for LED lamps used for warehouse lighting, the luminous flux may need to reach thousands of lumens to meet the needs of large-area lighting.
color temperature
Color temperature determines the color appearance of light. In Kelvin (K) as the unit, a lower color temperature (such as 2700K - 3000K) will produce warm white light, giving people a warm and comfortable feeling, and is often used in home bedrooms, restaurants and other places; while a higher color temperature (such as 5000K - 6500K) is cool white light, closer to natural daylight, suitable for offices, factory workshops and other environments that require bright and clear lighting. Foreign customers will choose the appropriate color temperature based on their usage scenarios and personal preferences.

Color rendering index (CRI)
The color rendering index measures how well a light source restores the color of an object, with a value ranging from 0 to 100. The higher the CRI, the closer the color of the object under the light will be to its color under natural sunlight. For example, in art galleries, high-end clothing stores and other places, LED lights with a high color rendering index (generally CRI above 90) are needed to truly display the color of artwork or clothing; and for some warehouses that do not have high color requirements or basement lighting, a color rendering index of around 80 may be sufficient.

Longevity and reliability 

The life of LED lights is usually measured in hours. Generally, the life of high-quality LED lights can reach 25,000 - 50,000 hours. Foreign customers will pay attention to the stability of the lamps during long-term use and whether problems such as flickering and brightness attenuation will occur. For example, for commercial places such as hotels, shopping malls, etc., frequent replacement of lamps is not only costly, but also affects normal business operations, so they are more inclined to choose LED lamps with long life and high reliability.

Lamp Materials and Workmanship
The quality of a light fixture’s housing material affects its durability. For example, LED lights with high-quality aluminum alloy shells have good heat dissipation performance and corrosion resistance, and are suitable for use in complex environments such as outdoors; while lamps with plastic shells may be more suitable for indoor environments, and attention should be paid to their fire resistance and other properties. In addition, the process details of the lamps, such as whether the welding is firm and whether the sealing is good, will also affect the customer's purchasing decision.

2. Safety standards and certifications
Comply with local safety regulations
Different countries and regions have different electrical safety standards. For example, in the European Union, LED lights need to comply with CE certification standards, including the Low Voltage Directive (LVD) and the Electromagnetic Compatibility Directive (EMC). LVD ensures that the lamps will not cause electrical safety risks such as electric shock to users under normal use and possible fault conditions; EMC requires that the lamps will not generate excessive electromagnetic interference and will not be affected by external electromagnetic interference. The United States has requirements such as UL (Underwriters Laboratory) certification, and lamps that meet these certifications can be legally sold in the corresponding market.

Environmental protection and restriction of hazardous substances
Many countries pay attention to the environmental performance of products. For example, the EU's RoHS directive restricts the use of hazardous substances such as lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and their ethers in electronic and electrical equipment. Foreign customers are increasingly inclined to buy LED lights that meet environmental standards in order to comply with the concept of sustainable development.

3. Energy Efficiency
Energy Efficiency Rating
Many countries and regions have rating standards for the energy efficiency of LED lamps. For example, the EU energy label specifies energy efficiency ratings from A (most efficient) to G (least efficient). High-efficiency LED lamps can save a lot of energy costs in the long run. For foreign customers who focus on energy conservation and emission reduction, especially in areas with high energy prices, they will give priority to products with high energy efficiency ratings.
Power Factor
The power factor reflects the efficiency of the lamp's use of electrical energy. A high power factor (usually greater than 0.9) means that the lamp can use the input electrical energy more efficiently and reduce reactive power losses in the power grid. This is an important consideration for both power companies and customers who are energy-conscious.
