Introducing the next generation of linear luminaires

Product Features 

The product of hundreds of hours of study with customers, multiple designs and numerous prototypes - meet the Protecta X. Focusing on the benefits of LED technology and how it could be negatively impact through installation in a linear enclosure, our team sought to break away from linear enclosures for a superior performance. Boasting a market-leading lifespan and incredible lumen output discover some of the Protecta X's features, below. 
  • 120,000-hour maintenance free lifespan at 25 degC
  • > 90,000 maintenance free hours at 60 degC
  • The lumen output of a 4ft linear in a lightweight and slimline package using specialised optics
  • A targeted bright, white output with minimal spill light
  • Market-leading efficacy of = 135 lm/W
  • Up to 50% energy savings vs traditional fluorescent fixtures
  • Multiple beam distributions available

Built to survive in the worlds most arduous environments

Our ATEX and IECEx certified luminaire has been built using marine grade aluminium for exceptional performance in the harshest environments. Plus, with an ambient temperature range of 40 degC to +60 degC in standard models and -25 degC to +60 degC in the emergency variants, for hazardous areas - choose the Protecta X. 
Putting the Customer at the Centre

Before designing the Protecta X the Chalmit team carried out an extensive voice of the customer survey. The key piece of feedback that came back because of this was that customers wanted two things: effortless installation and simple maintenance. To solve this, our team designed three essential features.

Innovative Battery Stick
The Emergency Protecta X is powered by an innovative battery stick which can be easily slotted in and out of the side of the luminaire, even after if has been installed on site, and without needing to access/ open the driver enclosure. 
Front Access Panel
Gone are the days of removing everything from a linear Enclosure, including the LED array, to install wiring. The Protecta X's front access panel means there's no need to take the Enclosure apart - just take off the front panel, wire and go!
Single Wing Option

The Protecta X is available as a double wing luminaire as standard but a single wing version is also available. The single wing design is ideal for handrail mounting (approx. 0.8m)  as well as easy access for installation and maintenance.
