1. Brightness and Luminous Efficacy

**Brightness**: High-quality LED panel lights have high brightness, and luminous flux (measured in lumens, lm) is a key indicator. The higher the value, the brighter the light. 

2. Heat Dissipation Performance

**Heat Dissipation Design**: High-quality panel lights use efficient heat dissipation materials (e.g., aluminum alloy) and structural designs to prevent overheating during prolonged use, extending the fixture's lifespan.

**Temperature Control**: Premium fixtures maintain a moderate surface temperature during operation, ensuring performance and safety are not compromised.

3. Lifespan and Durability

**Lifespan**: High-quality LED panel lights typically have a lifespan of over 25,000 hours, reducing replacement frequency and maintenance costs.

**Durability**: Premium fixtures have strong anti-aging properties, with minimal light degradation over extended use.

4. Color Rendering Index (CRI)

- The Color Rendering Index reflects the light's ability to reproduce the true colors of objects. High-quality LED panel lights should have a CRI of 80 or above, with 90 or above being ideal for spaces requiring accurate color representation, such as art galleries or retail stores.

5. Color Temperature

Color temperature (measured in Kelvin, K) determines the warmth or coolness of the light. High-quality panel lights offer a range of color temperature options (e.g., 3000K warm light, 4000K neutral light, 6500K cool light) to suit different scenarios. MILANLUX also accepts customized LED chips, such as 10000K or 3500K, to meet diverse application needs.

6. Uniformity and Light Distribution

**Light Uniformity**: Premium panel lights provide even light distribution without noticeable dark spots or bright areas, ensuring comfortable illumination.

**Glare-Free Design**: High-quality panel lights use soft light designs to avoid harsh glare, making them suitable for prolonged use.
