NEW GENERATION OF LED LIGHTING FOR HAZARDOUS AREAS
Chalmit, manufacturer of lighting for harsh and hazardous environments, has launched the Protecta X LED luminaire
T
he new luminaire is said to be up to 50 per cent brighter than the
traditional linear lights on the market - it has user-definable light distribution, a lifespan of over 120,000 hours at 25 degrees Celcius, is easier to maintain, and thanks to an optional battery stick, can be installed in half the time. Chalmit is a supplier of lighting to
the oil and gas industry. Its luminaires are used by the sector’s leading companies, including Shell, BP, Adma, Opco and many more. The Protecta X is Chalmit’s largest ever investment in product development; with four patents pending, it is expected to lead to a whole new generation of LED lighting within the sector. Ken Eddleston, Chalmit’s lighting
product manager elaborates: “Traditional linear luminaires have dominated the low-level lighting of hazardous areas for over 50 years. But linear lights were originally designed to house fluorescent lamps. Since then, LEDs have come in, but the linear enclosure hasn’t really changed, leaving the performance of LEDs compromised. “We felt it was time to change all
this. So, we gave the luminaires a complete re-think, putting customer needs and light performance at the front and centre of our design process. Rather than accepting the constraints of a traditional linear enclosure, our design team started from scratch and asked, what design would ensure the absolute best from the LED?” The result is the Protecta X – a high
performing LED linear for harsh and hazardous applications.
SPECIALISED OPTICS The Protecta X has specialised optics which deliver the light of a four foot linear, in a lightweight and slimline luminaire package. The optics control the light, generating a highly targeted, bright, white output over the desired area, and limiting the amount of wasted spill light. The optics are available in a variety of distinct distributions, designed for key site applications, such as hand rail mounts for walkway illumination and localised lighting in low/medium bay applications.

output means fewer luminaires are required, which reduces installation and inspection times, and overall project costs. Furthermore, the Protecta X is 50 per cent more energy efficient than a fluorescent luminaire, reducing energy costs too. Chalmit has also developed an
emergency version of the product. The Emergency Protecta X has an innovative battery stick which slots into the side of the luminaire, eliminating the need to laboriously open the driver enclosure to access the battery. If battery issues arise, the stick can be simply removed or replaced in minutes, reducing maintenance times by a third. The position of the battery stick also means users can purchase the stick when they’re ready to use the luminaire. Eddleston explains why this is such an important feature: “A luminaire is often delivered to site
well in advance of project completion. However, the longer you leave a battery unpowered, the more likely it is to fall
into an unrecoverable deep discharge state, resulting in expensive and time consuming maintenance of the unit before it has even been used! We’ve eliminated this big problem; if they want to, users can simply purchase the battery stick when they’re ready to use the luminaire.”
OVERHEATING ISSUES The Protecta X also avoids the overheating issues of traditional linear luminaires, making it more likely to meet the stipulated 120,000 hour lifespan. Even at 60 degrees Celcius, it has a lifespan of 90,000 hours. Its LEDs and driver are housed in separate enclosures, extending the life of both components. Air gaps between the luminaire and central body prevent the collection of dust and particulates, which can also encourage overheating. Made of highly recyclable marine grade aluminium (rather than plastic), heat is conducted away from the new luminaire’s central body. These design features ensure the Protecta X has an exceptional ambient temperature range of -40 degrees Celcius to +60 degrees Celcius in standard models and -25 degrees Celcius to +60 degrees Celcius in emergency variants. Eddleston concludes: “Many hundreds
of hours of development time, 15 customer study groups and thousands of pieces of customer feedback have gone into creating the Protecta X. The result is a luminaire which delivers on every front. This is truly a step change moment in the development of low level lighting for hazardous areas.”
