“Lighting sheet” is a general industry term that describes high-quality reflective aluminum that is fabricated to meet specific optical properties for use in various lighting applications. Lighting sheet provides maximum light distribution and helps reduce energy consumption. Reflective aluminum lighting sheet surfaces range in total reflectivity from 84% to 98%, with a variety of finishes available that offer specific optical values:

What is Lighting Sheet?

Made from high purity aluminum with a mirror-like surface, lighting sheet provides unique photometric qualities to control light. When installed behind a light source, lighting sheet specifically reflects and directs the light, just like a glass mirror. Along with silver, aluminum is the most reflective metal available.


Lighting refers to either artificial light sources, such as lamps, or to natural illumination of interiors from daylight. Lighting is one of the largest sources of energy consumption, accounting for a significant part of all energy consumed worldwide.


Reflection is the change in direction of a wavefront at an interface between two dissimilar media, causing the wavefront to rebound into the medium from which it originated. Common examples include the reflection of light, sound, and water waves. Reflection of light may be specular (i.e., mirror-like) or diffuse (i.e., not retaining the image, only the energy) depending on the nature of the interface.

Diffuse Reflection

In a flat mirror, a parallel beam of light changes its direction as a whole, while still remaining parallel; the images formed by a flat mirror are virtual images of the same size as the original object. Reflection of light may be specular (i.e., mirror-like) or diffuse (i.e., retaining only the energy, not the image) depending on the nature of the interface. 

Specular Reflection

In specular reflective aluminum, a beam of light reflects off the surface at an angle of reflection that is equal to its angle of incidence. That is, if the beam of light is shining on the surface at a 30° angle from vertical, then it reflects from the point of incidence at a 30° angle from vertical in the opposite direction.
