Here’s where the thought process starts…
Mid winter on the East coast of Australia somewhere!
Tom, a hard working tradesman started on the road at 6AM, and, due to his workload,
has not eaten all day. Navigates his vehicle towards McDonalds Drive through.
Though his menu selection has yet to be made, his body is preparing for the banquette ahead. His mouth is preparing for sustenance by salivation and his attention is
being focused towards edible treats that lie in the not too distant future.
Mary and Luke, quarrelsome and competitive 6 year old twins, escape
from their mothers parked car in the centre of McDonald’s congested Car park, and
head straight for the front door in order to be the first inline for the New Toy of the moment. Leaving mother to follow in hot pursuit, abandoning, their Aunty Em to stay in the car.
With Tom taking his order through the window of the Drive through and
nesting his spoils in the passenger’s seat, slides his vehicle into Drive and
promptly heads across the car park in order to make a quick getaway. At the same time,
appeasing his bodies request for sustenance, dips his hand into the bag of fulfilment to find the chips.
Simultaneously, Mary, displaying high emotions of joy and happiness by
emulating her toy of preference in flight as high as her arm can reach and
amazed by the flashing red eyes. Dashes, towards the car where Aunty Em is
sitting awaiting the next round of mayhem from the twins.
This is where the story begins…
What are the vertical illuminances within the carriageway?
Tom, as good and responsible driver as he is, is being diverted by natural instinct.
Mary and Luke are being driven by other distractions, yet all are on the same field of play.
Assisting in the visual senses of all parties is the Key to this success.
In order to assist Tom, the good lighting design engineer has provided
more than adequate Vertical Illuminance, minimised any Glare, and created
High Uniformity over the entire site. "Etcetera" "Etcetera" "Etcetera"
Therefore, Tom is assisted to see Mary, as she is slipping out at a great rate of knots between
the parked vehicles directly out side the building of contentment.
Needless to say, with Luke following directly behind Mary heading towards Aunty Em.
How deep does your Lighting Designer think?
Toy of preference!
With the below is a quick snapshot of what correct photometric testing
can look like compared to... Hmmmm something that is more likely to come from a
test lab at a bar using a beer coaster.

From Wikipedia, the free encyclopaedia
The lux (symbol: lx) is the SI unit of illuminance and luminous emittance, measuring luminous flux per unit area.
It is equal to one lumen per square metre.
In photometry, this is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface.
It is analogous to the radiometric unit watts per square metre, but with the power at each wavelength weighted according to the luminosity function, a standardized model of human visual brightness perception.
In English, "lux" is used in both singular and plural.

The following applies to all current suppliers—those who have been issued with a supplier code number prior to 1 March 2013.
From 1 March 2013
A three-year transition period will apply to current suppliers.
Current suppliers will be permitted to label devices with the C-Tick or A-Tick until 29 February 2016.
Current suppliers will be permitted to keep devices labelled with the C-Tick or A-Tick on the market with their current label. Devices labelled with the C-Tick or A-Tick before the end of the transition period on 29 February 2016 and in accordance with the existing requirements will not need to be relabelled.
From 1 March 2016
The new arrangements will apply to all suppliers.
Note: Supplier identification can be the supplier’s supplier code number (‘NXXX’). This may be replaced with any of the following:
> Australian Company Number (ACN)
> Australian Business Number (ABN)
> Australian Registered Business Number (ARBN)
> Australian business name and address
> personal name and address in Australia

Minimum Energy Performance Standard (MEPS)
As a reminder: The phase-out of 50W dichroic 12V halogen lamp!
The first stage of phasing out non-compliant extra low voltage halogen reflector lamps commenced on 1 October 2010. From this date, all halogen mirror reflector lamps such as the 12V 50W MR16 dichroic lamp must achieve the prescribed Minimum Energy Performance Standard (MEPS)
Minimum Energy Performance Standards (MEPS) will require the average measured wattage for extra low voltage 12V tungsten halogen multifaceted MR16 dichroic reflector lamps to be no more than 37W.
As of 14 April 2012 the 50W dichroic or mirror back reflector 12V halogen lamp used in many homes and commercial premises will be phased out.
The phase-out will see a ban on importation of the 50W MR16 lamp.
However existing stock already in Australia may continue to be sold.
Alternatives include using the same lamp shape and type with a 35W rating or a Reputable Brand LED lamp.
This information sheet clarifies the requirements for emergency lighting and exit signage on designated emergency evacuation routes on construction sites.
Principal contractors have management and control of construction sites and therefore have the primary obligation to ensure lighting is sufficient for workers to safely evacuate in emergencies and permit emergency or repair personnel to access the site. Unlike finished buildings, evacuation routes on construction sites often contain construction materials, electrical switchboards, portable equipment and other obstacles.
On sites where natural lighting is insufficient, evacuation lighting is normally provided by installing battery powered emergency lighting and exit signs. AS/NZS3012 Electrical
installations on construction sites and demolition sites, clause 2.7.3, sets out that a minimum light level of 20 lx be provided for a minimum of one hour following the loss of normal lighting.
This minimum level applies to the site’s designated evacuation routes. Emergency lighting should also be installed at or next to site switchboards to help restore normal lighting after a fault occurs.
Note: the 20 lx is an average light reading and can be determined using the advice given below.
Worker evacuation must be considered in the project’s planning phase. The principal contractor should make electrical contractors aware of the project’s evacuation lighting requirements during the construction wiring tender process. These requirements should take into account that evacuation lighting may need to be relocated at various construction phases.
As part of the site’s emergency response plan the principal contractor should designate evacuation routes for the various work areas. The routes should be regularly reviewed
over the life of the project to ensure they remain effective as the site layout changes.
In multi-storey buildings any active stairway will be used by personnel during an emergency, so each active stairway should be treated as an evacuation route.
When evacuation lighting is required
Site evacuation routes require evacuation lighting where:
• work is outside full daylight hours (evacuation lighting may need to be installed as the year progresses and days shorten), or
• natural lighting does not maintain the minimum lighting level being 20 lx (eg basements, internal passageways or shading from near by buildings).
Note: If any work area, including under temporary support structures (eg formwork decks), is not sufficiently lit by the evacuation route lighting additional emergency lighting should be installed to light the work area to allow safe exit.
Exits signs must not be positioned more than one metre above or two metres in front of the exit. If the evacuation route turns, or does not lead directly to an emergency exit, then exit direction arrow signs that point towards the emergency exit must be installed at each change of direction.
Exit signs, including exit directional arrow signs, should be the internally illuminated battery back-up type so they are visible through smoke. In specific circumstances, however,
clause 6.3 of AS/NZS 2293 Emergency escape lighting and exit signs for buildings, states that externally illuminated signs may be suitable. This is only in areas that have appropriate means for automatically exhausting or excluding smoke. Exposure to open air does not meet this requirement.
Externally illuminated signs, where permitted, must be directly illuminated by an emergency light.
Reusing evacuation light fittings
Often, evacuation light fittings are reused from previous sites or other temporary installations (eg from completed lower floors of a multi-storey site).
As the lamps and batteries age, the drop in light output must be managed to ensure minimum evacuation lighting levels are maintained.
Protecting evacuation lighting
Evacuation light fittings should be manufactured from impact resistant material
(eg polycarbonate) or be fitted with mechanical protection (eg wire cages).
Periodic testing of evacuation lighting
Evacuation lighting must be inspected and electrically re-tested every 6 months, including a discharge test to ensure evacuation lighting maintains the 20 lx lighting level for at least one hour after the loss of normal lighting.
Records of testing should be kept on site or made available for auditing.
