Final Report Lot 9: Public street lighting - Amper

Option 1 (stock base):
HPS retrofit lamps exist for High Pressure Mercury and in this option we assume that they are
used in existing luminaries, this means that sales of all HPM lamps is excluded. These retrofit
lamps consume about 10 % less power and produce about 40 % more light. So retrofitting
increases the probability of non compliance of the installation with existing regulations and
standards.
This option is of course hypothetical, because it still allows to sell new HPM luminaires for
HPS retrofit lamps. Therefore in practice, option 13 should be considered.
Option 13:
In this combination, there is assumed that, in addition to option 1, all sales of HPM luminaires
are excluded, as well for new projects as for replacement luminaires.

Option 2 :
In this option we assume that all HPS-lamps are types with enhanced lumen output, the super or
plus lamps (see chapter 4). This is calculated as well for the stock as for the new sales.
7.2.1.2 Using improved HID light sources
Option 3 (new sales base):
This option assumes that improved MH lamps are used to replace all MH lamps in category S as
described in chapter 6.2.1. (We also assumed 110 lm/W efficacy).
The calculated impact on the performance parameters is low due to the actual low market share
of MH lamps (see chapter 2) but it can become significant if these lamps become more popular
in future.
