The Mercian is a high-performance wall-mounted luminaire designed for durability and efficiency. Its robust construction features a die-cast aluminium body paired with an impact-resistant, flame-retardant, UV-stabilised prismatic polycarbonate cover. This combination ensures the luminaire is vandal resistant and well-suited for demanding environments such as walkways, entrance areas, commercial premises, educational institutions, and healthcare buildings.
Engineered for optimal photometric performance, the Mercian achieves wide luminaire spacing—up to six times the mounting height—providing efficient illumination over larger areas. Its strong pressure die-cast LM2 aluminium body prevents distortion during installation and helps preserve the IP65 rating, maintaining reliable protection against dust and water ingress. The luminaire is easy to install using external stainless-steel brackets fixed at two lower points, positioned outside the gasket line to maintain the IP rating. Optional photocell control enhances energy savings, and tamper-resistant cover screws are available for added security.
The Mercian complies with the Ministry of Defence’s JSP482 Chapter 8 Document for ‘Category C’ areas, reflecting its suitability for secure and critical environments. It also features SmartScan wireless technology, which eliminates the need for control cabling, making it ideal for retrofit projects. The luminaire carries a high IP65 ingress protection rating and offers an IK10 impact resistance rating, ensuring resilience against mechanical impacts. It supports presence detection up to 8 meters, further enhancing its energy efficiency and adaptability.
Lighting specifications include a prismatic cover optic delivering 3,300 lumens with an efficacy of 110 lumens per circuit watt. The LED power consumption is 26 W with a total circuit power of 30 W, and the product offers colour temperature options of 4000 K and 5700 K with a high colour rendering index (CRI) of 80+. The Mercian provides maintained emergency lighting with a lumen output of 250 lm and a three-hour duration, supported by a reliable Nickel Metal Hydride (NiMH) battery. Rated for a long operational life of 100,000 hours (L70/B10), this luminaire is certified to meet UKCA and CE standards. It contains a light source classified under energy efficiency class B, balancing performance with environmental considerations.
