Bright does not always equal light
When we think about outdoor lighting, brightness is often the first thing that comes to mind. But what feels “bright enough” to the eye isn’t always what counts when it comes to safety, compliance, and energy efficiency. That’s where lux testing plays a crucial role. By measuring the actual light levels that reach the ground, lux level testing allows us to see if an installation is performing as intended – and whether it meets the requirements of Australian Standards such as AS 1158 for public areas, AS 2560 for sports facilities, and AS/NZS 4282 for managing obtrusive light.
What Exactly Is Lux Testing?
Lux is the measure of illuminance – how much light falls on a given surface. Unlike lumens (the amount of light a lamp produces) or candela (the intensity in a specific direction), lux reflects how a space actually appears under lighting. In simple terms, it answers the question: is there enough usable light here? This is the figure lighting consultants, councils, engineers, and contractors rely on when assessing compliance.
Why It Matters
Accurate lux level testing does more than tick a compliance box. Adequate light levels help prevent accidents in public spaces, ensure car parks and roadways feel safe, and make sure players on sports courts can perform at their best. It also helps prevent costly mistakes: a design that overshoots target levels wastes energy and creates unnecessary glare, while one that falls short can result in rejected permits or expensive retrofits.
Typical lux levels by space
Different environments demand different light levels. A corridor needs far less light than an office desk, and a training field far less than a competition pitch. The table below shows typical values from the Australian Standards. By measuring real-world performance against these targets, we can see exactly where a project stands. For workplaces, see commercial lighting audits.
| Space | Standard | Typical requirement* |
|---|---|---|
| Corridors and stairs | AS/NZS 1680.1 | 40 lx (80–160 lx commonly specified) |
| General office work | AS/NZS 1680.1 | 320 lx |
| Fine detailed work | AS/NZS 1680.1 | 600–800 lx |
| Football, training to competition | AS 2560.2.3 | 50–200 lx |
| Local pathways | AS/NZS 1158.3.1 | Category PP3 |
| Car parks | AS/NZS 1158.3.1 | Category PC2 |
* Typical maintained average illuminance. Pathway and car park requirements are set by the AS/NZS 1158.3.1 lighting category chosen for the site. PP3 and PC2 are common selections, and each category also sets minimum values.
The Testing Process
At Spaces At Night, lux level testing is carried out using calibrated Hioki 3425 and Yokogawa 51001 lux meters. Measurements are taken systematically across a grid, covering the entire area under assessment. These results are then compared against the relevant Australian Standard, and any shortfalls are identified along with practical recommendations – whether that means re-aiming fittings, adjusting output levels, or upgrading equipment.
A Real-World Example
In one recent project, we assessed a community tennis facility where players had raised concerns about visibility. Our testing showed that average brightness was within the target range of AS/NZS 2560.2.1, but uniformity was lacking – meaning some areas of the court were much darker than others. With a few carefully planned adjustments to existing floodlights, the facility not only achieved compliance but also delivered a much better playing experience, without the need for costly replacements.
Looking Ahead
Lux testing isn’t just about meeting today’s requirements – it’s also about future-proofing assets. Lighting standards continue to evolve as technology advances and as councils place more emphasis on sustainability, energy savings, and community amenity. By having a reliable set of test results on record, asset owners can demonstrate compliance, plan upgrades more strategically, and avoid unexpected costs down the track. In this way, light level auditing becomes an essential part of long-term asset management, not just a one-off box-ticking exercise.
Independent, Unbiased Advice
As independent lighting consultants, our only focus is on delivering accurate, impartial test results. We don’t sell fittings or push unnecessary upgrades. Instead, we provide councils, engineers, and town planners with the clarity they need to move forward confidently, whether it’s for planning permits, rebate applications, or long-term asset management.
If you’re considering a lighting upgrade or simply need confirmation that your installation is performing as it should, our team can help with independent lux testing.
