lighting before accord

Parabolics are designed to direct light into the cut-off zone, while restricting light into the shielded or glare zone. In other words, parabolics deliver light to the work plane and suppress high-angle brightness.

Due to the high-angle cutoffs as shown in Figure 1., parabolics can create areas where light is concentrated and areas where there is no light. These areas of minimum light are referred to as “dark spots”.

lighting with accord

To eliminate the “dark spots” and sharp cutoffs created by parabolics, Cooper Lighting designed accordTM. The accordTM provides a feeling of spaciousness and does not substantially increase glare, as shown in Figure 2.

The accordTM provides the following advantages:

•Improved visual perception

•Enhanced space

•Attractive contemporary design

•Significant energy savings
