► HPS 150W lamp
Based on available data for HPS lamps of different power, we found that the relation between
power and weight of this type of lamp is fixed between a specific band width (like the HPM
lamps). If this relation is applied for calculating the weight of the 150W lamp, the result
corresponds to producer-specific data. Therefore, the BOM starts from the total weight of the
lamp and assumes an identical material composition (in terms of percentage of weight) as the
HPS 70W lamp. Exceptions on this calculation method are made for the mercury-content in the
lamp, which is a fixed amount and thus independent of the lamp power (based on
company-specific data), and for the lamp base, which is an E40 type for the 150W lamp
(instead of E27 for the 70W lamp). The BOM that is composed this way was compared with
BOMs of specific suppliers and showed no significant discrepancies.
The table below shows the BOM as is taken into account for the environmental assessment.
