Why is color maintenance so important in Cove applications and why are most Cove fixtures failing the test?

In a cove application multiple linear fixtures are used in a row. The fixtures are hidden behind a soffit and only the light output of the fixture is seen as it

illuminates a surface. The majority of cove applications cascade the light on a white surface, taking advantage of maximum reflectivity.

Uniformity is the key to a successful cove application. Many factors affect the uniformity of an installed cove; whether the fixtures are pointed correctly, consistent CCT and wattage of the fixtures and whether they have been mounted consistently. When a cove is first installed all these factors can be examined and adjusted as required.

However, once the installation is complete, what happens to the quality of light and the integrity of the design over time? With traditional plastic-based LEDs, used in most cove linear fixtures on the market, after less than 10,000 hours (as little as 1-1/2 years) the color of each LED will shift due to a break-down in the substrait of the LED. Binning cannot predict the amount or nature of shifting among the LEDs.
