Raytec’s SPARTAN range of Intelligent Emergency Linear and Bulkhead products have been approved to Class I Division 2 (UL/CSA) standards. The new products will complement Raytec’s existing range of UL/CSA certified products and means a full range of standard and emergency hazardous area products for the North American market are now available. SPARTAN Intelligent Emergency products offer a number of key features; High output, long duration emergency performance Up to 100% light output in emergency mode Self-testing – batteries are cycled automatically LED indicator – communicates the luminaires health status...

Earlier in 2018, all products in the SPARTAN range were recertified to comply with an update in the ATEX directives (EN 60079-28:2015) referred to as ‘op-is’. But what exactly does this mean, and more importantly, why does it matter? What is op-is? Op-is focuses on the ignition risk caused by optical radiation from LEDs. Light beams may not normally be perceived as dangerous, but as technology develops, LEDs are becoming increasingly powerful and their beams more intense. In certain environments this could present an ignition risk as particles in the... Read More

Raytec are delighted to launch a new range of ‘intelligent’ emergency luminaires. Initially available in the Linear and Bulkhead product ranges, the new intelligent emergency products feature an innovative automatic testing function and take safety and performance of emergency luminaires to the next level. Featuring a microprocessor programmed to automatically cycle the batteries, the new products perform three different testing procedures to ensure the luminaire is operating correctly and the emergency battery system is functioning at it’s optimum; Commissioning test Three charge and discharge cycles are carried out automatically at...

Emergency Ex lighting plays an important role in maintaining the safety of hazardous area locations, and the well-being of those who work in them, by providing back-up illumination when the primary power source fails. In this article we take a closer look at how the latest ‘intelligent’ emergency luminaires can improve performance of emergency systems, ultimately increasing safety and reducing risk on-site.   What Is an Intelligent Emergency Luminaire? ‘Intelligent’ emergency luminaires feature a built-in microprocessor which automatically cycles the emergency batteries, checks the health status of the luminaire and...

Raytec have recently launched a new range of High Power Floodlights and Bay luminaires which offer full DALI capability. As some of the first hazardous area luminaires to incorporate DALI technology, this article looks further into what makes a luminaire ‘DALI enabled’ and the benefits this can bring. What is DALI? A Digital Addressable Lighting Interface (DALI) is a digital communication protocol developed specifically for the lighting industry. DALI brings a host of new possibilities into hazardous area lighting applications by allowing groups of luminaires to be controlled together, or... Read More

When specifying LED replacements for your traditional flood and bay luminaires, the most important factor to consider and compare is ‘delivered lumens’ i.e. the amount of useable light, discounting losses and wasted light. Traditional Ex luminaire manufacturers often only quote lumens at source, i.e. lumens at the bulb before it’s travelled through any lensing. But traditional Ex light fittings are typically only around 60% efficient in transmitting useable light out of the luminaire, meaning that the delivered lumens can often be up to 40% less than quoted. In addition, consumption... Read More
