Discussion of results
The relative distribution of impacts over the life cycle for stock luminaires is similar to that of
sales luminaires.
When comparing total impacts per unit of product sales versus stock (Table 102) we notice that
in category F, impacts per average product unit are higher for sales compared to stock, while in
categories M and S this is the other way around. This can be explained by relatively lower
impacts for LPS luminaires compared to HPS luminaires (see table Table 83 and single
EcoReports for LPS and HPS on www.eup4light.net) and the assumption that for new sales
LPS are being replaced with HPS luminaires. When however considering the functional unit
(see tables Table 97, Table 99, Table 101) impacts per functional lumen output of sales
luminaires are lower compared to existing stock luminaires. Besides the difference in average
weights for luminaire types sales versus stock, this is also related to the assumption that stock
luminaires have generally worse LMF and UF (97,5% compared to new products).
