ATEX Lights designed for


  1. Mounting: The Somerville line-up offers users 4 Installation options. The standard universal mounting bracket allows 360° rotation within cradle. Alternatives include a surface-mounting bracket, pole slip fitters for area lighting application, and pendant loops for ATEX high bay usage and reduced fitting variation across site.

  2. Heat Dissipation: The Somerville series has the wide ambient usage tolerance of -40° to 65°C, through LED chips spacing and the driver being placed externally on the back of the light fitting it provides excellent heat dissipation and lower junction temperatures.
  3. Environmental Protection: It offers IP66 protection by using aluminium body that comes with corrosion resistant paint finish - Salt spray testing reports available.
  4. 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.
