Final Report Lot 9: Public street lighting - Amper

Table 156 and Figure 14 indicate that HIDs only account for a very small share (1,6–1.7%) of
the total EU-25 lamp sales volume. The average efficiency of HID lamps varies considerably
between national markets depending on the relative share of low-efficacy mercury vapour
lamps compared to the high-efficacy metal halide and high-pressure sodium lamps (IEA, 2006).
In Europe mercury vapour lamp sales account for 27% of all HID lamps at present (Figure 15).

Figure 15: Evolution of share of High Intensity Discharge lamps in EU-25, 1999-2004
(Source: rescaled based on population from original ELC sales data for the Western
European market)
Similar to the volume of ELC lamp sales the total value of ELC sales was rescaled to EU-25
based on population (Figure 16). While the volume of total ELC lamp sales in EU-25 is
augmenting in the period 1999-2004, the corresponding total value of the ELC EU-25 lamp
market is declining on average with 0,4% every year in the same period due to price erosion.
