The Stirling Series Portable luminaires are ATEX-certified floodlights, work lights, and task lights. Supplied with a power-cable and compatible with a range of input voltages, they provide a high-powered lighting solution, allowing for continuous operation without the need for battery charging.
It is designed to be a robust, yet light-weight solution for illuminating internal & external jobs in the oil & gas, petrochemical, marine & offshore, & heavy industry sectors.
The floor stand allows for quick positioning on any horizontal flat surface, while the magnetic stand gives alternative flexibility for quick attachment to any ferrous surface, e.g. ship hulls, or structural steelwork.

DESIGN FEATURES
ATEX Lights designed for PURPOSE
The Stirling 3 Portable's design goal was to offer users flexible mounting and excellent illumination levels in a convenient, lightweight package. Two stand types, floor and magnetic, are available. Two Mounting Options - The Stirling 3 Portable offers Floor Stand and Magnetic Stand. It is able to rotate 270° within the cradle, easy illumination for nearly any temporary usage. Input Voltage - Three options are available for input voltage to give you flexibility in each area of work. Input Voltage Ranges: 100-277VAC, 24-48VAC/DC, 10-30VDC. Lumen Performance - The Luxeon 5050 LED chip delivers 130lm/W and a stable lumen-maintenance of L70 ≥120,000 Hours. Combing this efficacy with three power options (30W to 60W), ensures that one of the three output options will meet the application requirements. Fixture Weight - At a low 5kg fixture weight ensures it is a portable light fitting in hazardous area environments. Zone 1 - Designed to meet the stricter Zone 1 requirements, ensures the light can be used for either Zone 1 or Zone 2. NOTE: The Stirling Portable is also available with a rechargeable, integrated battery - see also our Sinclair Series. For low-bay and pendant applications - see Stirling and Stirling 3 Series.
TYPICAL APPLICATIONS
Chemical Stores
These lights provide sufficient coverage for vehicle loading and unloading of Hazardous Substances while providing resistance against hazardous conditions.
Inspection Pits
Inspection pit lighting design must consider illumination of the underside of the vehicle as well as the ground, ease of maintenance and impact resistance.
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.
Paint Shops
ATEX lights for paint shops and spray booths. Lux levels and specialist paint shop and spray booth lights for hazardous-area product finishing.
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.

Details are for the standard non-dimming driver. Fixture weight excludes bracketry.
IK rating format is housing / front face; IK10 front face when fitted with the wire guard.
Wire-in-wire-out products are supplied with one non-armoured ATEX certified gland and one ATEX certified blanking plug. Armoured cable glands are an option; contact Kellwood.
The stated cable size applies to the standard gland; armoured cable may vary.
Hazardous area certified product modifications are typically limited to bracketry, to keep certification. Products are supplied with OEM nameplates, codes and documentation corresponding to the certification.
If more than one modification is required, separate each modification with a hyphen at the end of the product code.
Modifications which affect light output have separate photometric files identified with +(modification).
Alternative drivers may be available. Contact the office for further details.
If the product is customised, the code is altered.
Contact the office for further information on driver parameters.
