how to choose high lumen LED lights?

Choosing the right high CRI and high lumen LED lamp requires considering many factors. Here are some suggestions:
Clearly define the usage scenario
Home lighting: Different rooms have different lighting requirements. Living rooms usually require higher lumens to provide an overall bright environment. At the same time, high CRI can make the colors of furniture such as TVs and sofas more realistic. Generally, you can choose LED lamps with 3000-5000 lumens and CRI above 90. The bedroom pays more attention to the warm and comfortable atmosphere. The lumen can be slightly lower, 2000-3000 lumens is enough. The CRI should also be guaranteed to be around 90 to restore the true color of clothing.

Commercial lighting: Shopping malls and supermarkets require high lumens to illuminate large areas and attract customers' attention. They usually require lamps with lumens of 5000-10000 and a CRI of 90-95 to show the true color of the goods and promote sales. Office lighting generally requires uniform and bright light, with lumens between 3000-5000 and a CRI of around 90 to reduce visual fatigue and improve work efficiency.
Industrial lighting: Factory workshops and other places require high lumens to ensure clear visibility of the work area. The lumen requirement is usually above 5000, and the CRI depends on the specific work content. For example, for work with high requirements for color recognition, the CRI needs to be above 90; for general production work, a CRI of 80-90 can also meet the needs.

Pay attention to lamp parameters
Lumen value: Choose the appropriate lumen value according to the usage scenario and space size. Generally speaking, the larger the space and the higher the lighting requirements, the greater the lumen value required. You can refer to the lamp product manual or consult the merchant to determine the appropriate lumen value.
Color rendering index (CRI): For scenes with high requirements for color reproduction, such as art galleries, museums, photography studios, etc., you should choose LED lamps with a CRI of more than 95; for ordinary home and commercial lighting, a CRI of 90-95 usually meets the needs.

Color temperature and glare: Choose the appropriate color temperature according to different scenes. For example, a family bedroom is suitable for using 2700-3000K warm white light to create a warm and comfortable atmosphere; a living room can choose 3500-4000K neutral white light, which looks bright and comfortable; offices, shopping malls and other places are suitable for using 4000-6500K cold white light, which can provide clear and bright light. At the same time, choose lamps with low glare values to reduce irritation to the eyes.

Heat dissipation performance: Good heat dissipation is the key to ensure the life and performance of LED lamps. Check the heat dissipation design of the lamp, such as whether there are heat dissipation fins and whether the heat dissipation material is good. High-quality heat dissipation materials and reasonable heat dissipation structures can effectively reduce the chip temperature and improve the light efficiency and service life of the lamp.
Service life: The service life of the lamp is also an important consideration, generally expressed in hours. Choosing LED lamps with long service life can reduce the frequency and cost of replacing lamps. The service life of high-quality LED lamps is usually more than 20,000-50,000 hours.

Long-term cost considerations: Although the purchase price is higher, high-quality LED lamps have higher energy efficiency and longer service life. In the long run, they can save electricity bills and the cost of replacing lamps, and have a higher cost-effectiveness.
In addition, you can also check the product's certification, such as 3C certification, energy-saving certification, etc., to ensure that the product meets relevant standards and requirements. If conditions permit, you can also actually observe the lighting effect of the lamp to make a more accurate choice.
