[Part E – Physical design and materials] Street environment 297
Luminaires
Luminaires must conform to the relevant British
Standards (for example, BS EN 60598 and BS
EN 62722, etc) and demonstrate optimum
performance for their intended use.
The luminaire form and shape should not be
obtrusive nor out of character with the general
street scene.
Any electrical load installed on the TLRN such as
a luminaire must have an appropriate ELEXON
charge code to permit correct energy settlement.
The luminaire must be oriented in accordance
with the manufacturer’s recommendation (for
example to avoid glare). Our preference is for
luminous intensity classes of G4 to G6 unless
otherwise agreed by our technical approvals
manager.
Control of light pollution
Light pollution or obtrusive light must be avoided.
The following lighting conditions are to be avoided:
• High light intensity in an inappropriate location
• Poorly positioned or oriented luminaires
• Undesirable highway lighting spilling out on to
the surrounding environment
• Uplighters – uplighting may only be used with
the specific consent of TfL
• Tree or invasive building illumination
Intrusive glare should be controlled by complying
with BS 5489 and BS EN 13201 standards.
All street lighting on the TLRN should comply
with obtrusive light limitations for exterior
lighting contained in the Guidance Notes for the
Reduction of Obtrusive Light published by the
Institution of Lighting Professionals.
Electrical
Where lighting columns are serviced by a
distribution network operator (DNO) supply, a
secondary isolator is to be fitted in the column
base compartment in order that electrical
isolation can be safely achieved without the need
to touch the DNO cut-out.
Independent connection providers can be used to
help reduce delays in scheme works, approvals may
be obtained via the technical approvals manager.
All electrical installations must be installed and
maintained in accordance with BS 7671 and
BS 7430.
Good practice and the reduction
of street clutter
We are determined to reduce the amount of
street furniture that might confront all road
users, therefore street lighting columns might
also be employed in supporting, for example:
• Traffic signals
• Crossing controls
• Footway luminaires
• Trixi safety mirrors
• CCTV cameras
• Bus flags and timetables (subject
to approval of TfL Buses)
• WiFi communications
