Engineered light that performs and saves

Lighting is the single built-environment element with the greatest impact on occupant experience, energy expenditure, and regulatory compliance — yet it is routinely underspecified, delegated to product suppliers with a commercial interest in overselling, or simply replicated from one project to the next without analysis. Apex Current Solutions takes a fundamentally different approach. Our lighting design service begins with a photometric and lux calculation study, not a product catalogue, and concludes with a commissioned, documented installation that delivers the maintained illuminance levels your space demands at the lowest practicable energy consumption.

Every lighting design we produce is grounded in AS/NZS 1680 Interior and Workplace Lighting, the NCC Section J energy efficiency provisions, and AS/NZS 2293 emergency and exit lighting requirements where applicable. For commercial and industrial projects, we prepare formal photometric calculation reports using industry-standard DIALux or Relux software, with illuminance distribution maps, uniformity ratios, glare indices, and energy density figures documented for certifier and base building review. Our designs are inherently buildable — specified to luminaires with verified LM-79 photometric files and delivered with a commissioning methodology that confirms in-situ performance against the design intent.

Architectural Lighting Design & LED Retrofit

Architectural lighting shapes how spaces feel — the quality of light at a retail display, the drama of a feature facade, the productivity-supporting uniformity of an open-plan office. Our design team works collaboratively with architects, interior designers, and project managers to translate spatial concepts into a lighting layout that is technically rigorous and aesthetically resolved. LED retrofit projects receive the same photometric rigour as new-build specifications: existing luminaire schedules are audited, replacement lamp and driver compatibility is confirmed, and a maintained lux verification is performed post-installation to validate the retrofit against the original design intent.

Photometric Design, Lux Calculations & DALI Controls

• AS/NZS 1680 compliant photometric reports with DIALux or Relux illuminance mapping and uniformity analysis
• DALI-2 dimming control systems with daylight harvesting, occupancy sensing, and scene programming
• LED retrofit design with maintained lux verification and energy modelling to NCC Section J
• Emergency and exit lighting design to AS/NZS 2293.1, including 90-minute battery backup and test-point scheduling
• Architectural feature lighting: facade, landscape, retail display, hospitality, and heritage applications

DALI (Digital Addressable Lighting Interface) control systems represent current best practice for commercial lighting control, offering individual luminaire addressability, group dimming scenes, daylight harvesting integration, and fault reporting that DALI-2 certification extends to sensors and input devices. Apex Current Solutions designs and commissions DALI-2 systems to IEC 62386, programming scene hierarchies and daylight harvest setpoints in collaboration with the building automation contractor. The energy savings delivered by well-commissioned DALI with occupancy and daylight harvesting consistently exceed 40 per cent over uncontrolled fluorescent baselines — savings we quantify in our design documentation with reference to monitored post-occupancy data.

Energy Savings, Emergency Lighting Compliance & Lifecycle Accountability

Lighting accounts for 20 to 40 per cent of commercial building energy consumption, making it the highest-return energy efficiency intervention available to most asset owners. Our LED and controls upgrade proposals are presented with full lifecycle cost modelling: capital cost, annual energy savings at current tariff, maintenance cost reduction from extended lamp life, and simple payback period. We identify available NABERS energy rating impacts and state government energy efficiency scheme certificates — including VEET, IPART ESS, and REES where applicable — that materially reduce net project cost. Emergency lighting compliance, including the mandated six-monthly functional test and annual 90-minute discharge test to AS/NZS 2293.2, is managed under our maintenance programme, with test certificates issued to the building owner and forwarded to the relevant fire authority on request.

If your project demands lighting that performs to a documented standard, saves measurable energy, and remains fully compliant across its service life, Apex Current Solutions has the design expertise and installation capability to deliver it.
