Previously, the international lighting industry had no clear guidelines to guarantee the exchangeability of LED modules from different manufacturers. Since its foundation in 2010, the consortium has developed specifications for LED module interfaces. These interfaces permit simple integration of LED modules into luminaire designs and reduced design and system costs.
