New generation LEDs for hazardous areas

Chalmit, a leading manufacturer of lighting for harsh and hazardous environments, has launched the Protecta X LED.

New generation LEDs for hazardous areas

The company said that the “revolutionary”, new luminaire is up to 50% brighter than any traditional linear light on the market. “It has user-definable light distribution, a lifespan of over 120,000 hours at 25 degC, is easier to maintain, and, thanks to an optional battery stick, can be installed in half the time,” the company stated.


Part of the Hubbell Harsh & Hazardous group, Chalmit explained that the Protecta X is its largest ever investment in product development. With four patents pending, it expects Protecta X to lead to a whole new generation of LED lighting within the sector.


“Traditional linear luminaires have dominated the low-level lighting of hazardous areas for over 50 years,” said Ken Eddleston, Chalmit’s lighting product manager. “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 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 – the highest performing LED linear for harsh and hazardous applications ever developed.”


The Protecta X has specialised optics that deliver the light of a 4ft 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 mounted from handrails for walkway illumination and localised lighting in low/medium bay applications.


This higher, more focused output means that fewer luminaires are required, reducing, installation, inspection times and overall project costs. Furthermore, the Protecta X is claimed to be 50% more energy efficient than a fluorescent luminaire, reducing energy costs too.


Chalmit added that it has also innovated with the emergency version of the product. “The Emergency Protecta X has an innovative battery stick that slots into the side of the luminaire, eliminating the need to laboriously open the driver enclosure to access the battery,” the firm stated.


“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.”


Ken Eddleston explained 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.”


The Protecta X is also claimed to avoid the overheating issues of traditional linear luminaires, making it more likely to meet the stipulated 120,000-hour lifespan, and even has a lifespan of 90,000 hours at 60 degC.


Its LEDs and driver are housed in separate enclosures to extend the life of both components. Air gaps between the luminaire and central body are designed to prevent the collection and 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 are intended to ensure that the Protecta X has an exceptional ambient temperature range of -40 degC to +60 degC in standard models and -25 degC to +60 degC in emergency variants.


Ken Eddleston concluded: “Many hundreds of hours of development time, 15 customer study groups and thousands of pieces of customer feedback have gone into the Protecta X. The result is a luminaire that delivers on every front. This is truly a step-change moment in the development of low-level lighting for hazardous areas.”
