ATEX Lights designed for

PURPOSE

Designed to be compact and versatile, the Stephenson Series is ideal in applications such as inspection pits. spray booths, chemical stores and similar hazardous areas.

High CRI and efficacy is achieved through quality components and SEOUL light sources.

  1. Emergency/Motion Sensor Options:
    The Stephenson 5 series offers an optional integrated 3 hour remote-test maintained emergency function.
  2. Impact Resistance: Risk of early failure is mitigated by using a shock and vibration-resistant aluminium alloy housing capable of withstanding an impact of up to 10 Joules (IK10). A tempered glass lens provides impact resistance up to IK08. An optional stainless steel guard increases this to IK10.
  3. Thermal Performance: Careful PCB design ensures effective heat dissipation from the LED chips. This lowers the junction temperatures, improving lumen maintenance and increasing the lifespan to the product.
  4. Mounting Options: The Stephenson Series is available with a range of mounting options; twin surface mount brackets, twin eye bolts, twin pipe clamp mount, stanchion mount, clamp mount.
