Final Report Lot 9: Public street lighting - Amper

examine the minimum requirements that are included in standards but the ALARA (as
low as reasonable acceptable) principle is actually not included in standards. In some
cases the opportunity for installing new luminaires can be used to increase lighting and
comfort of outdoor lighting, the final result could be an increase in comfort without
energy saving at system level.
8.1.5 Required new measurement standards
There is a need to draw up a standard for measuring the energy efficiency of ballasts for HID
lamps. CELMA mentioned that this will be done in future.
8.1.6 Suggested additional research
Tunnel lighting was excluded from the study for reasons mentioned in chapter 1, but it is
recommended to carry out further research outside the scope of this directive. It should focus at
installation level and the maximum use of daylight and creating a systematic approach at EU25
level.
It is also recommended that further research is done on the ecological impact of street lighting
and the reduction of sky glow for astronomic observation.
It is also recommended to carry out further research on monument and architectural outdoor
lighting:
- taking into account the 'colour' of the light source and the environment. A blue light
source will be useless to lit a green tree. Therefore installation requirements are
particular useful for these applications.
- taking into account that only the target area needs to be lit.
- light pollution should be taken into account and is also very related to installation
requirements.
- the annual product sales is probably low (
