Lighting specifications
This sections looks at the different parameters that need to be specified for a successful lighting design.
The following is a list of things to include in specifications for contractors.
Lighting specifications
| Minimum IP rating of 65 with fitted moulded gaskets
rather than using extruded materials fixed with self adhesive
backing tape, etc |
| Total light output ratio of greater than 65 per
cent |
| Preferably have zero wasted light output for lighting
on pathways, car parks roads, etc |
| Total energy losses equal to, or less than 10 per
cent |
Equipment specifications
| Equipment should be of rugged construction with materials and
finishes appropriate to its place of location |
| Must be vandal resistant where appropriate |
| Have a manufacturers warranty of no less than 5 years for the
paint finishes and no less than 7 years for the lantern and pole
construction, excluding lamps and control gear that shall have a
minimum or 1 year warranty |
| Have full cut-off optics and/or light beam control |
| Have a style that is in keeping with the neighbourhood (avoid
the overuse of mock heritage lanterns) |
Family of lights specifications
| Lighting components to be 'reusable' and/or 're-cyclable' |
| Parts to be interchangeable between models |
| Lights to come with installation kits |
| Lighting to come with pre-installation kits where appropriate,
e.g. in-ground luminaires |
| Lighting photometric efficiency laboratory tests/
internationally accredited/ independent lab tested/ certification
required to be provided |
| All equipment should comply with the Waste Electrical and
Electronic Equipment Directive of the European
Union. |
Ratings
| Touch - temperature ratings - 65 degrees max. (in-ground lights
only) |
| Copper content of aluminium in lighting fixtures shall be less
than 0.1 per cent (i.e. LM 6) |
Types of light required
| Street lights |
| In-ground lights |
| Up lights |
| Wash lights |
| Bollard lights |
| Pedestrian pole top lights |
| Feature lights - e.g. façade lighting |
Lamp source
| Metal Halide |
| Compact Fluorescent |
| High pressure sodium |
| Halogen |
| LED |
Environmental and energy conservation considerations
- Use the correct V
or P category
- Ensure that there is no over lighting - do not guess, consult a
lighting expert if necessary
- Base the lighting design on peak night time vehicle traffic or
pedestrian traffic flows where possible
- Use good quality luminaires with a high light output ratio and a
high IP
rating
- Use flat glass luminaires with zero upward wasted light output and
where possible change to a lower illumination level or category outside
peak traffic hours whilst still maintaining a safe environment
- Ensure regular maintenance of equipment and budget for replacement
e.g. cleaning, lamp replacement at recommended intervals etc. For
example, if the luminaires were cleaned at 12 monthly intervals the
design output of the luminaires would be 20 % higher than that currently
used by the Auckland City Council designs (which would result in fewer
lights and lower energy costs)
- Use equipment that can be broken down for recycling (WEEE directive)
