How to Avoid Dim LED Downlights
When purchasing LED downlights, it’s common to experience dim lighting. This can be due to the color rendering index (CRI) of the lamp. To avoid this issue, it’s important to select a lamp with a CRI of 80 or 90, as these lamps tend to provide optimal lighting. Additionally, it’s recommended to ask for the specific CRI of the lamp before making a purchase. By keeping these factors in mind, you can ensure that your LED downlights provide bright and clear lighting for your space.
Don’t Overlook Installation
When it comes to selecting lamps and lanterns, such as LED downlights, it’s crucial to consider the installation method based on the project ceiling conditions. Downlights can be installed as either embedded or bright downlights, depending on the desired lighting effect and space height. For lower spaces with a height of around 2.8m, recessed downlights are a better option, as they are hidden within the ceiling and only the mask part is exposed, creating the illusion of a higher ceiling. On the other hand, for taller spaces with a height of at least 6m, such as hotel lobbies, where the ceiling thickness is greater.
here’s an updated table with the recommended installation height for each scenario:
| Scenario | Illumination Requirement | Power Requirement | Installation Type | Recommended Installation Height |
|---|---|---|---|---|
| Home living room | 500-700 lux | 12-15W | Recessed | 2.5-3 meters |

| Restaurant | 300-500 lux | 10-15W | Surface-mounted | 2-2.5 meters |
| Hotel lobby | 200-300 lux | 10-15W | Recessed or surface-mounted | 3-4 meters |
| Museum | 150-300 lux | 10-20W | Recessed or surface-mounted | 3-4 meters |
Based on Illuminance Requirements
When selecting LED lighting, it’s important to consider the illuminance requirements of your space. Illuminance depends on the intended use of the space, and you can calculate it by using the formula Illuminance (lux) = Lumen Output ÷ Area (m²). You should also check product specifications for lumen output and consider the color temperature of the light, which can affect the mood and atmosphere of the space. By choosing LED lighting that meets the illuminance requirements and complements the space’s intended use, you can ensure adequate illumination and enhance the overall aesthetics and functionality of the space.
Sure, here are even more precise illuminance requirements for different lighting scenarios:

Confirming Compliance with Local Safety Standards
It’s common for many buyers to overlook the importance of checking the certification of lighting fixtures before making a purchase. This could mean that the purchased lighting fixtures may be non-compliant or unsafe. For example, the embedded downlight category is included in the National Mandatory Product Certification Catalog and must pass the 3C certification with a 3C logo before being sold. In addition, certifications such as GB, ISO9001, and CE are also important factors that should not be overlooked when selecting lighting fixtures.
Different countries have different requirements for LED lighting certifications and safety standards. Below is a table outlining the certification and safety requirements for LED lighting fixtures in different countries:
