Final Report Lot 9: Public street lighting - Amper

pronounced, i.e. the apparent consumption of sodium lamps is more than twice as high as the
actual consumption indicates (133,2%-134,3% in 2003-2004).
As the MEEuP report (VHK, 2005) states, significant differences between the actual
consumption and the apparent consumption may occur.
ELC will be asked if they have a further explanation for this discrepancy.
Annual sales growth rate
Total ELC EU-25 sales figures Table 156 (ANNEX J) indicate an average annual growth rate of
4,62% in the period 2000-2004 for all lamp types.
Looking into more detail at lamp types applicable in street lighting, i.e. the HID sales data,
Table 11 shows that globally the HID’s grow at a somewhat faster pace than the average of the
total lamp market: 5,1% annually. Differences in annual growth rates occur though between the
different HID lamp types: while the sodium lamps grow at a rate close to the global HID sales,
metal halide lamps display a much stronger growth rate (+13,8% on average in 2000-2004),
while the mercury lamp sales exhibit a mean decline of 1,7% over the same period.
Note these observed annual growth rates apply to the global HID lamp market and as the exact
share of HIDs applied in street lighting is not known these figures can only be regarded as
indicative. The absolute numbers serve as an upper limit for the annual sales of lamps for street
lighting.
