The criterias which influence the environmental performance of the LED fixture system could be assessed through the life cycle assessment methodology, the ratio for each criteria is multiplied by 0 or 1 for “no/yes” criteria, or by the number the system scores on the criteria (1–5). The individual scores for the criterias are then summed together to get the total score for the system.
