The color of the shell or housing of LED linear lights, whether black or white, does not directly affect the brightness of the light output. The primary purpose of the shell is to provide protection for the internal components and to contribute to the overall design and aesthetics of the fixture.

The brightness of LED linear lights is determined by factors such as the light output of the LEDs themselves, the efficiency of the LED technology, the design of the optical components (such as lenses or diffusers), and the power supply driving the LEDs. These factors primarily influence the amount of light emitted and the distribution of that light.

However, the color of the shell can indirectly affect the perceived brightness in certain situations due to its impact on light reflection and diffusion. Here are a couple of considerations:

  1. Reflection of Light: A white shell tends to have higher reflectivity compared to a black shell. If the shell reflects a significant amount of light, especially in situations where the light is directed towards a surface or area, a white shell can help enhance the perceived brightness by reflecting more light into the surroundings. Conversely, a black shell may absorb more light, potentially resulting in a slightly lower perceived brightness.
  2. Contrast and Ambient Lighting: The color of the shell can influence the contrast and overall perception of brightness in a space. For example, if the LED linear lights are installed in an environment with white walls and a white shell is used, the lights may blend in and provide a more uniform distribution of light. On the other hand, a black shell may create a visual contrast against the surroundings, which can make the light appear more focused and intense.

It's important to note that the impact of the shell color on perceived brightness is relatively minor compared to other factors such as the light output and characteristics of the LEDs themselves. When selecting LED linear lights, prioritize factors such as the lumen output, beam angle, and color temperature to ensure the desired level of brightness and lighting effect.
