The Somerville Series LED ATEX floodlights offer a versatile lighting solution for Zone 2 (zones 2 and 22) hazardous area applications.
Available in power options ranging from 80W to 150W, these floodlights use high-efficacy Luxeon 5050 LED chips and offer wide (120°) or medium (80°) beam distributions. This allows for precise illumination across various mounting heights while minimising energy consumption.
Each unit comes standard with an individually certified ATEX gland and blanking plug. Designed for flexibility, the fixtures also support wire-in/wire-out configurations and can be machined for a range of inlet thread sizes, making them suitable for both basic installations and projects requiring compliance with specific site standards.
Additional adaptability is provided through a variety of mounting options, including universal bracket, surface, pole, and recessed mount configurations.

DESIGN FEATURES
ATEX Lights designed for PURPOSE
With a wattage range of 80W to 150W, the Somerville Series is designed to be a general purpose ATEX Rated (Zone 2) floodlight. Features include: 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. Heat Dissipation: The Somerville series has the wide ambient usage tolerance of -40° to 55°C. LED chips spacing and the driver being placed externally on the back of the light fitting provides excellent heat dissipation and lower junction temperatures resulting in a lumen maintenance of L70 ≥ 120,000 Hours. Environmental Protection: It offers IP66 protection by using aluminium body that comes with corrosion resistant paint finish - Salt spray testing reports available. 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.
TYPICAL APPLICATIONS
Chemical Stores
These lights provide sufficient coverage for vehicle loading and unloading of Hazardous Substances while providing resistance against hazardous conditions.
Distillery
Lighting for Distilleries must find a balance between style and function; lights must offer optimum performance in vapour-filled environments.
Grain Processing and Storage
Lighting for grain processing and storage rooms must work in the presence of flammable dust, meeting regulations for hazardous areas and food production.
Oil Rigs
Oil rig lights need to perform in harsh environments where safety is paramount. We offer a variety of LED ATEX explosion-proof lighting for oil rigs.
Tank Farms
Lux levels and hazardous area Zone 1 and Zone 2 lighting for tank farms. We have the product range and experience of lighting design needed for tank farms.
Oil Refinery
For oil refinery lighting and for the petro-chemical sector, Kellwood Lighting offer a range of marine grade LED ATEX / IECEx approved lighting products.
