Illuminating 2025: A Year in Review and Key Trends Shaping South Africa’s Lighting Industry in 2026
As we step into a new year, it’s worth reflecting on the conversations, insights, and knowledge shared across the lighting community in 2025. At IESSA, our mission remains clear: to empower lighting professionals with the expertise, tools, and perspectives they need to thrive in a fast-evolving industry.
Here’s a look back at some of the major themes we explored in 2025, and what they signal for the opportunities ahead in 2026.
AI-Powered Lighting Assistants: A New Era of Smart Illumination
This year, we unpacked how AI is reshaping lighting, from automated fault detection to predictive maintenance and occupant-centric lighting control.
Key takeaway: AI is shifting lighting management from reactive to proactive. In 2026, expect deeper integration with building management systems and more accessible AI tools in local infrastructure projects.
The Future of Energy Efficiency: LED Innovation in South Africa
We highlighted how LEDs continue to dominate the efficiency conversation, with advances in lifespan, tunable lighting, and sustainability.
Key takeaway: With rising energy costs and load pressure, 2026 will place even greater emphasis on retrofit solutions, lifecycle cost savings, and compliance with tightening standards.
Basic Concepts of Luminaire Design
Lighting professionals revisited core design principles, optics, thermal management, materials, and electrical safety.
Key takeaway: Luminaire design is becoming more multidisciplinary, blending engineering, sustainability, and human-centric performance.
Understanding Hazardous Location Lighting
Our 2025 guide broke down classifications, risks, and compliance considerations across industrial and mining environments.
Key takeaway: As South Africa strengthens workplace safety regulation, competency in hazardous lighting remains essential, with higher demand for certified products and trained professionals.
Lighting for Roads and Precincts in South Africa
We unpacked local standards, safety needs, poles, optics, and modern technologies improving public spaces.
Key takeaway: Municipalities are accelerating the adoption of energy-efficient and smart street lighting. Projects combining efficiency, safety, and data-driven management will grow.
Understanding Photometry
This educational article highlighted the science of measuring light—luminous flux, illuminance, luminance, and distribution.
Key takeaway: With advanced measurement tools becoming more accessible, lighting professionals need to stay sharp on photometric interpretation and testing.
Engaging with Lighting Design
We encouraged professionals to rethink lighting as both a technical and artistic discipline that influences behaviour, mood, and performance.
Key takeaway: Human-centric lighting is increasingly driving project decisions, especially in workplaces, hospitality, and education.
Lighting Design as a Critical Element for Green Buildings
This piece explored how lighting contributes to energy credits, user wellbeing, and long-term sustainability outcomes.
Key takeaway: Green Star New Build v2 is raising the bar. Lighting specifications will play a larger role in achieving credits related to energy, comfort, and resilience.
Why Green Star New Build v2 Matters to the Lighting Industry
We explained the major updates introduced by the GBCSA and what they mean for project teams.
Key takeaway: The shift toward holistic sustainability pushes lighting professionals to rethink efficiency, glare, daylight simulation, and lifecycle impact.
Key Trends for South Africa’s Lighting Professionals in 2026
Some of the key trends to look out for in 2026 for lighting professionals.
-
Smart Lighting Becomes Standard Practice
AI, IoT integration, and sensor-driven systems will move from “nice-to-have”
to expected features across commercial and public projects. -
Greater Demand for Skills Development
With evolving standards, new certifications, and advanced technologies,
continuous learning will be essential. IESSA’s accredited courses will be
central to this growth. -
Energy Resilience Takes Centre Stage
Load shedding pressures underscore the need for low-consumption systems,
adaptive lighting, and robust infrastructure for both public and private sectors. -
Human-Centric Design Drives Value
Clients want spaces that support health, productivity, and wellbeing.
Tunable lighting and evidence-based design will continue gaining traction. -
Sustainability Requirements Intensify
From Green Star to municipal guidelines, 2026 will bring tighter regulations
and stronger incentives for sustainable lighting choices. -
Cross-disciplinary Collaboration Grows
Architects, designers, engineers, planners, and suppliers will work more closely
as lighting becomes integral to spatial experience and environmental performance.
Lighting the way forward, with IESSA
2025 was a year of growth, innovation, and shared knowledge for the lighting community. As we move into 2026, IESSA remains committed to championing excellence, supporting professional development, and fostering a collaborative, future-ready industry.
Together, let’s continue shaping a brighter, smarter, and more sustainable lighting landscape for South Africa.
IESSA represents South Africa internationally and thereby acts as the National Committee of the CIE (Commission International De L'Eclairage). South African Experts on various topics in the lighting technology field serve on the CIE international committees responsible for the development of standards for the different aspects of illumination.
Membership of IESSA is open to both individuals and organisations active in the lighting industry of South Africa. You need to be a Lighting Professional to join IESSA. Group membership is open to any educational, scientific, technical, professional, institution, public, commercial, municipal, or parastatal entity that is actively involved in the lighting industry.
