Can I use a dimmer to control a sensor?
No - Dimmers are designed with a minimum load requirement, hence when a sensor turns off the light, the load detected by the dimmer will be insufficient to maintain the control.
My LED strip KIT, which I have just cut to (a shorter) length, is momentarily "blinking" or "flickering" when I turn the LED OFF.
This event is not a safety issue and typically occurs when the LED Strip load falls below the threshold of the driver design limit, which will result in a minor capacitive discharge in the form of the LED strip momentarily "blinking" or "flickering" when the power is turned off. When cutting LED strips KITS, it is always important to calculate the remaining LED load to reconfirm its compatibility with the existing driver, as driver changes may be required with moderate reduction in loads,
As there is no global performance standard for dimming devices (other than safety and EMC) it is important to consulate with your supplier the compatibility of the devices you propose to install. Minimum loads and dimming performance limits are critical ratings that must be considered when using such devices.
Yes and these warranty extensions are detailed on the relevant product installation sheet or web page.
This first point of contact should be the place of original purchase, after which they will be responsible to coordinate the warranty communication with the SAL Commercial Customer service team.
Absolutely, careful attention is required when installing exterior products to ensure the designated aiming orientation is correct and allows for the natural cleaning of debris/dust from the glass visor surface, in particular when aimed in an upward direction. Products aimed in an upward direction can result in a build-up of dirt on the glass visor, which in turn can thermally stress the product if it is not routinely cleaned. Any aiming restrictions can be found with the installation instructions located in the product carton and or on the relevant product web page.
Simple answer is NO. Although documented as “hours” Lumen maintenance with LED products is calculated through the combination of LM79, LM80 and TM21 reporting methodologies and reflects as a guide “useful” time duration of the light source. Rated life on the other-hand (when stated) denotes the rated average LED failures over a given time, shown typically shown as rated survival hours.

(MEPS) Minimum Energy and Performance Standards is a Commonwealth Government Greenhouse and Minimum Standards Act, which focusses on the reduction of inefficient electrical sources, one of which is traditional Lighting equipment.
Regulated products for Lighting are: Fluorescent lamp ballasts, linear fluorescent lamps, transformers and converters for halogen lamps, compact fluorescent lamps and incandescent lamps. For more information on MEPS www.energyrating.gov.au/products/lighting
The simple answer is Yes. Electrical products are just like your vehicle when it comes to maintenance requirements. They both collect dust and require cleaning and they both have components that require routine inspection and adjustments. Please refer to any specific maintenance instruction on the SAL Commercial installation sheet or web site.
What does anti-microbial mean and why this is important for medical lighting in Australia?
Silver is a well-documented antimicrobial, that has been shown to kill bacteria, fungi and certain viruses. It is the positively charged silver ions (Ag+) that possess the antimicrobial effect. Silver ions target microorganisms through several different modes of action.
In healthcare applications where medical lighting, examination lighting, minor procedure lighting, minor surgical lighting and surgical lighting are critical in the transmission of pathogens by human hands. Being a high touch surface, medical lighting products require an extra-ordinary level of protection to try mitigate accidental contamination.
Brandon Medical Coolview, Astralite, Astramax and Quasar products incorporate the anti-microbial substance into the light head during manufacturing. This inhibits the growth of and proliferation of microbes and bacteria, whilst the silver ions destabilise the cell membrane.
This prevents the bacteria from multiplying. Tests have shown that 99% of bacteria and germs are destroyed using the Sanitized® and Biomaster® active substance.
This mark, which is mandatory for in-scope lighting and electrical products in Australia, which confirms the product complies with applicable safety and EMC standards.
Suppliers Declaration of Conformity. A SDOC is typically a document that a supplier generates to confirm mandatory safety and performance testing for a particular product has been completed, in lieu of distributing expansive original test reports, which generally are best read by qualified persons. At a minimum a SDOC for lighting equipment should present the relevant Safety and EMC test reports and test report numbers, together with the relevant model numbers of the equipment being offered. The SDOC should be supplied and endorsed by the authorised supplier of the equipment.
Humidity can play havoc with electronic circuits (more commonly known in light as LED’s) This data can be found on SAL installation sheets and should be considered before installation of equipment.
What is WELL V2 - WELL Building Standard Version 2?
There are 4 primary lighting features that are defined in the WELL Building Standard V2 that lighting designers, and engineers can use to meet the necessary criteria. The WELL Light concept promotes exposure to light and aims to create optimal lighting environments for biological, visual and mental health.
There are eight (8) features (L01-L09) comprised in this Light concept of the WELL Building Standard that define and prescribe specific technical requirements. These technical requirements will require confirmation from lighting manufactures so that lighting designers and engineers can properly determine if their design will meet the Standards needs.
These 4 primary lighting features relevant for lighting designers, engineers and manufacturers. Each of these has a separate FAQ available:
SAL Commercial has a WELL AP ( Accredited Professional) on staff. Simon Richardson, WELL AP, is available to assist with WELL Building Standard questions.
What are the WELL Building Standard V2 Electric Lighting Glare Control Guidelines? (L04 Electric Lighting Glare Control)
L04 Electric Lighting Glare Control is focused on managing glare control using combinations of strategies as careful space planning and lighting design can minimise the amount of glare experienced by occupants.
The Standard describes L03 as: “This WELL feature requires projects to manage glare by using strategies, such as calculation of glare and choosing the appropriate light fixtures for the space.”
The Requirements set our are:
Each luminaire meets one of the following requirements for regularly occupied spaces at light output representative of regular use conditions. Wall wash fixtures and concealed fixtures, installed as specified by manufacturer’s data, as well as decorative fixtures may be excluded from meeting these requirements:
a) 100% of light is emitted above the horizontal plane.
b) Classified with Unified Glare Rating (UGR) of 16 or lower.
c) Luminance that does not exceed 6,000 cd/m2 at any angle between 45 and 90 degrees from nadir.
This can be represented per luminaire in a table by the manufacturer as per the following example.
Remember the luminaire has to meet ONE of those requirements and documentary proof the results are required.
In additional Option 2; Space Consideration states that:
The following requirement is met in all regularly occupied spaces:
a) Unified Glare Rating (UGR) of 16 or lower.”
What are The WELL Building Standard V2 L08 Electric Light Quality Guidelines?
L08 Electric Light Quality is focused on characteristics of lights such as colour rendering, colour quality and flickering.
This has a lot more considerations to it however the first part at least - Enhance color rendering quality - is straightforward.
The Standard describes L08 as: “This WELL feature requires projects to take into account characteristics of electric light used in the space, such as color rendering and flicker.”
For Part 1 - Enhance Color Rendering Quality - There are different requirements for Circulation Areas and All areas BUT Circulation Areas.
For all A Grade commercial office fitouts in Australia this would be common-place today. The WELL Building Standard formalises this requirement specifically ensuring that this basic requirement is met, if for some reason a vale engineering process was attempting to offer an under performing alternate light source.
The specific requirements set out for all but circulation spaces are:
All luminaires (except decorative fixtures, emergency lights and other special-purpose lighting) meet at least one of the following color rendering requirements. If tunable white lighting is used, the requirements are met at 1,000K intervals from the lower end (with a minimum of 2,700K) to the higher end (with a maximum of 5,000k):
This can be represented per luminaire, in a table by the manufacturer as per the following example.
Remember the luminaire has to meet at least ONE of those requirements and documentary proof the results are required.
Part 2 - Manage Flicker - with an additional 2 Points available is very prescriptive in its requirements.
Find Part 1 of L08 Electric Light Quality here
The specific requirements set out are:
All luminaires, in combination with the appropriate controls (except decorative lights, emergency lights and other special-purpose lighting), used in regularly occupied spaces meet at least one of the following flicker requirements:
Option b) - is the one we are most likely to depend upon in Australia
b. Recommended practices 1, 2 or 3 as defined by IEEE standard 1789-2015 LED.9
IEEE Standards Association. IEEE Std 1789-2015 - IEEE Recommended Practices for Modulating Current in High-Brightness LEDs for Mitigating Health Risks to Viewers. 2016. doi:10.1109/IEEESTD.2015.7118618
As a guideline a minimum frequency of 90 Hz at 10% light output intervals from 10% to 100% light output
Essentially this constitutes a statement of compliance for LED luminaires with the IEEE Standard 1789-2015 with supporting values for full light output.
Many drivers from reputable manufacturers also provide data on the driver which provide clarity with respects to their compliance to Part C:
c. Pst LM ≤ 1.0 and SVM ≤ 1.6 for indoor applications per NEMA 77-2017.10,11
Below is an image of a Tridonic branded driver with the compliant area marked:
L03 Circadian Lighting Design is focused on maintaining circadian health and ensuring an alignment with the circadian rhythm of individuals with the day-night cycle. This part L02 is about providing users with appropriate light exposure.
The Standard describes L03 as: “This WELL feature requires projects to provide users with appropriate exposure to light for maintaining circadian health and aligning the circadian rhythm with the day-night cycle..”
The Requirements set our are:
For workstations used during the daytime, electric lighting is used to achieve the following thresholds:
The following light levels are achieved for at least four hours (beginning by noon at the latest) at a height of 45cm above the work-plane for all workstations in regularly occupied spaces:
This is a summary of those requirements from the IALD:
EML Stands for Equivalent Melanopic Lux and is defined by the photopic lux multiplied by a melanopic ratio, EML - LxR
To calculate the equivalent melanopic lux (EML), multiply the visual lux (L) designed for or measured in a building by this ratio (R): EML = L × R. For example, if incandescent lights provide 200 lux in a space, they will also produce 108 equivalent melanopic lux. If daylight is modeled to provide the same visual brightness (200 lux), it will also provide 220 equivalent melanopic lux.
See also: Table L2: Melanopic and Visual Response which provides more descriptive information: To calculate the melanopic ratio of light, start by obtaining the light output of the lamp at each 5 nm increment, either from manufacturer or by using a spectrometer. Then, multiply the output by the melanopic and visual curves given below to get the melanopic and visual responses. Finally, divide the total melanopic response by the total visual response and multiply the quotient by 1.218
For more information read the following Measuring and using Lighting in the Melanopsin Age by Luca, RJ et al.
ElectroMagnetic Compatibility, which defines the use of different electronic devices (such as electrical appliances, medical equipment, LED’s and drivers etc) to operate without interference with other devices. This is a mandatory label (and testing) requirement for Australian Lighting equipment covered by AS/NZS CISPR 15. ACMA also recognise equivalent standards CISPR 15 and EN 55015.
IP (or Ingress and Protection) are an international standard reference which defines how well an electrical product seals itself against the intrusion of foreign bodies and moisture. The first digit I stands for intrusion of a solid object and the second digit P stands for the protection against moisture. In brief the higher the rating the more secure the product is against these elements.
As a guide IP20 is suitable for basic interior spaces eg: office areas, where IP55 and above would be suitable for exterior equipment such as floodlights.
For more information please refer to AS 60529.
For the digital LED world L70 is simply a measure of time that the light source will be reduced to 70% of its original (or initial) output. You will also see documented L90, which represents the measure of time where the product is reduced to 90% of its original (or initial output).
In street terms LM79 is a set of methodologies for laboratory testing of solid state luminaires, which will result in CCT, CRI, system power, luminous flux and distribution being reported.
In street terms LM80 is the test method for measuring lumen maintenance for a LED light source at the actual component level ie the LED.
(thermal ambient) is the recommended maximum environmental thermal limit for the safe continued operation of an electrical device. The ta rating can be found on the rating label and installation sheet, which is located on the relevant product web page. Typically, you will find ta ratings of 25 degree C for Interior products, where ta ratings of up to 50 degree C can be found for exterior products. Operating products beyond their designed ta limit is not recommended as it will stress the product components beyond their rated limits, resulting in reduced product performance or premature failure.
In street terms TM21 is a method to extrapolate the LM80 lumen maintenance data beyond the actual test duration and determine a projection of lumen maintenance as referenced by L70 or L90 (70% or 90% of the initial light source output).
This is a product that requires the installation of an earth to be compliant to AS/NZ 3000.
This is a product that does not require the installation of an earth to be compliant to AS/NZ 3000, as the product is a double insulation product.
An IK rating of a lighting product is covered by EN 62262 and is a measure of the impact resistance of a product. In brief the test process measures a products mechanical impact (impact energy joules) limits against a known mass and varied distances. As a guide the higher the IK rating (limit 10) the higher the products ability to withstand impact force.
High IK rated products (IK10) would be seen used in environments such as vandal prone installations, prisons as a guide.
Earth leakage current is an important electrical safety measurement and care should be considered when calculating earth leakage values. This data can be found on SAL Commercial installation sheets or for more details on the calculating method go to AS/NZ 60598.1.2013 table 10.3.
Like traditional HID circuits, LED despite the smaller electrical loads has its own limits when it comes to in-rush currents, which must be considered with all electrical circuits. This data can be found on SAL Commercial installation sheets.
This is an emergency light that remains ON at all time and remains ON during a supply failure for the designated time as per AS 2293. Maintained lights are typically (but not limited to) EXIT signs.
A non-maintained emergency light is one that is only used (on) for emergency lighting, hence in the event of a mains (supply) failure, the emergency light source will be activated.
(CRI) in street talk is a measure of how an illuminated object appears to the eye. As a guide the higher the CRI rating >85, the closer the illuminated object is when compared to standardized daylight. Typical CRI value available are: CRI70 for outdoor recreational sports, CRI80 for interior task areas, >CRI90 clinical observation tasks.
Si (k) denotes the colour temperature of a light source referenced against a black body radiator.
In street terms colour temperature is how warm or cool you see the light source.
eg : warm colours are typically 2700-3000k, which would generally be used in residential interior spaces.
cool colours are typically around 4000k, which would generally be used in office interior spaces.
cold colours (daylight) are typically 5000-6000k, which would generally be used in exterior spaces.
Lumen (lumen lm) is the total light out of a light source measured as (initial lumens) representing the base or NEW lamp source lumens. (Rated lumens) is then measured after 100 hours usage for traditional lamp sources and LED sources are represented by L70 or L90 ratings.
Lux (lx) is the unit measure for how much luminous flux (lumens lm), which in street terms is LIGHT falling on a given surface. Lux can be accurately measured by a calibrated Light meter
In line with SAL Commercial standard terms and conditions of sale the standard warranty is twelve (12) months, unless stated otherwise on the product installation sheet and web page.
The mandatory luminaire general requirements and testing is covered by AS/NZS 60598.1:2013. This standard addresses essential electrical and operating performance tests for a lighting product, which is a must when selecting lighting products.
This standard is in addition to specific product standards such as AS/NZS 60598.2.2-2016 and AS2293.1.2005 Emergency Lighting as an example.
As a minimum you should find all necessary electrical data to allow you to be informed about the electrical characteristics of the product to enable a safe and compliant installation such as RCM mark, company logo, voltage, line current, power, frequency, power-factor, country of origin, IP rating, batch number ta rating, cover ratings if applicable.

There many reason why to use an LED light source, however the two (2) headline reasons are;
(1) a significant reduction in electrical energy to achieve the same value of illumination and
(2) a significant reduction in operating costs.
