than its equivalent in legacy products. This lower temperature translates to better T ratings and ultimately a safer product and working environment. Lastly, maintaining consistent
performance under extreme conditions is an ongoing concern for LED lighting. These harsh environments often expose systems to vibration, shock, and extreme temperatures, impacting the reliability and longevity of luminaires. To address this issue, manufacturers must design thermally managed, robust products that can withstand these harsh environments.
The transition to LED lighting is an inevitable step
adherence to essential safety requirements for equipment in potentially explosive atmospheres.
ADVANTAGES OF LED IN EXPLOSIVE ENVIRONMENTS LED lighting is highly energy-efficient and consumes significantly less power than traditional, older lighting systems. This efficiency results in reduced energy costs, an important factor for industries relying on extensive lighting. Using energy-efficient LEDs will not only save up to 50% per year in energy costs, but also contribute towards a carbon net-zero journey. Additionally, the longevity of LEDs
translates to lower maintenance costs and fewer operational disruptions. While fluorescent lamps are relatively inexpensive, the costs associated with obtaining permits, powering down circuits and conducting the work, can become very costly. By contrast, LEDs minimise the need for maintenance and lamp replacements. This is especially true when these are bespoke modules designed to work within the luminaire, and not just a LED lamp. LED lighting also provides improved
visual acuity in the most hazardous areas, offering better colour rendering and directional light control. Enhanced visual acuity is critical in these environments, where accurate visual cues and colour perception can
significantly impact safety. A well-designed LED luminaire
will also contribute to higher energy savings owing to their increased compatibility with the use of controls. The lifespan of older technologies is negatively affected by users turning them on and off frequently. Some try to reduce maintenance costs by leaving lights illuminated continuously. LED luminaires are not affected by users turning them on and off many times a day, since they consume no power when off, and strike instantly with 100% light output.
CHALLENGES OF USING LED LIGHTING IN EXPLOSIVE ENVIRONMENTS Despite the benefits, implementing LED technology in explosive environments presents challenges. One such issue is ensuring compliance with stringent safety regulations. Explosive atmospheres demand lighting systems that minimise the risk of ignition, requiring the development and certification of LED luminaires that are specially designed for hazardous locations. This adds complexity and cost to the transition process. Another challenge is managing heat
dissipation. LEDs generate heat during operation, and effective thermal management is crucial in hazardous areas. The good news is that a well- designed LED system can run cooler
EMBRACING THE INEVITABLE TRANSITION The phase-out of fluorescent lighting has made the transition to LED technology an inevitable step, but manufacturers and end-users can collaborate to ensure a successful, safe and efficient transition. Design software can aid in the
compliance process supporting good lighting practices and standards. These simulations can demonstrate the lighting required for an area, and provide vital information regarding uniformity, colour rendering (CRI) and levels when emergency luminaires are needed.
THE FUTURE OF LIGHTING IN EXPLOSIVE ENVIRONMENTS As industries continue to evolve and adopt new technologies, embracing LED lighting in hazardous areas is a vital step towards enhancing safety, efficiency, and operational performance. Although challenges can be present, ongoing innovation and collaboration between manufacturers and end-users will pave the way for the widespread adoption of LED technology in critical environments. By embracing the inevitable transition and addressing the key hurdles, hazardous area lighting can move forward into a more sustainable, cost- effective, and safer future.
