Even though eggcrate louvers do share a cellular nature with parabolic louvers, there are fundamental differences. The cell walls of parabolics are curved, the cell walls of eggcrate louvers are flat. While the finish of the vast majority of parabolic louvers have a high percentage of specular reflectance, eggcrate louvers have either a diffuse finish, or are actually semi-transparent.

The cell walls of eggcrate louvers will block the view into the luminaire cavity at angles beyond the shielding angle. The reflectance of light off of the diffuse finish, or passage of light through the translucent cell walls provide a random distribution. Like lenses, eggcrate louvers brighten the ceiling but do not provide the controlled distribution required for visually critical tasks.

Eggcrate Louvers are appropriate for areas where brightness control is not critical. Large areas of ceiling can economically be covered to provide a sense of lightness and space. Different styles of Eggcrate Louvers are available to meet your particular needs and budget.
