Everything LIGHTING
Triangle are known for delivering large-scale lighting upgrades and planned preventative maintenance (PPM) programmes for complex, high-occupancy environments; particularly within the healthcare and education sectors.
​
We specialise in the integration and management of advanced DALI-based lighting control systems, enabling centralised monitoring, fault detection, and energy optimisation across thousands of luminaires.
Our team is experienced in working within live environments, where safety, discretion, and coordination with estates teams are critical.
​
From lifecycle replacements in major hospitals to full-scale LED upgrades in multi-site school estates, we provide tailored solutions that reduce energy consumption, lower maintenance costs, and improve long-term system resilience.
​
Whether it’s 50 fittings or 50,000, we approach every project with the same commitment to quality, compliance, and continuity; ensuring lighting systems remain safe, efficient, and future-ready.
