ATEX ZONE 1
SUTHERLAND SERIES
Explosion Proof LED High Bay Lighting
HAZARDOUS AREA FLOODLIGHT SYSTEM

Key difference: recommended if asymmetric optics are required, otherwise, consider Sutherland 2 or 3 Series
As one of our range of well-priced explosion proof lighting products, the group II, zone 1, Sutherland Series is an ATEX-certified light fitting, originally designed for high-install requirements.
Developed as lighting for hazardous locations, the Sutherland's value extends far beyond this basic application. 6 acute and wide-dispersion lens variants are available in symmetric and asymmetric configurations.
Here at Kellwood Lighting, our team is here to help you find the best light fittings for your project. You can enquire about the Sutherland Series via the link on the page. Alternatively feel free to speak to one of our team on +44 (0)1387 255816.

ATEX Lights designed for
PURPOSE
Ideal as lighting in the petrochemical industry but also suitable in animal feed warehouses and in engineering facilities, a stainless steel impact-grill is available for specification should the client be concerned by flying debris or mobile plant and equipment.
- Mounting: The Sutherland Series has 5 different installation options; universal bracket, surface mount bracket, eye bolt, in-line pipe connector and slip fit. These 5 separate mounting systems effortlessly widens its role to cover floodlighting and street lighting applications.
- Optics: There is 5 symmetric and a asymmetric optics offered across the Sutherland Series making it a versatile hazardous area light fitting.
- Impact Resistance: Risk of early failure is significantly lowered through the use of a shock and vibration-resistant tempered glass lens and industrial copper free aluminium alloy housing. Which can withstand up to 20J of force.
Environmental Protection: It offers IP66 protection by using aluminium body that comes with corrosion resistant paint finish - Salt spray testing reports available.
